17.1 not too shabby Sent from my iPhone using Tapatalk

As soon as I leave work I will stop by a station and we'll see what I get using cruise control and being light on the pedal. It looks like around 18mpg.. Sent from my iPhone using Tapatalk

Isn't it strange that people experience similar issues together.. So to gain access to the nuts hidden by the heat shield you might be able to use a hole saw which is the diameter of the socket you're going to use. I would take the hole saw and remove the drill bit from the middle. Use a long drill bit extension and hammer the hole saw up against the hidden nuts. When you have created a solid impression in the heat shield the hole saw should be sort of locked in place. Attach a drill and begin drilling the heat shield out. If it works the way I see it working in my mind you should be left with a perfect hole to access those nuts. Here are the hole saw and extension I'm referring to: http://www.toolnut.com/milwaukee-49-56-0043-1-hole-saw.html?utm_source=google_shopping&gclid=Cj0KEQiAlsrFBRCAxcCB54XElLEBEiQA_ei0DIJwY9yxBZyLbEz-6gKIIIfTQLUWLOSMiIpwV2LKPq0aAtF08P8HAQ https://www.zoro.com/milwaukee-bit-extension-all-hex-24-x-716-in-48-28-1060/i/G5136467/?gclid=Cj0KEQiAlsrFBRCAxcCB54XElLEBEiQA_ei0DPhaXvz2rZt2yS3nLBVz7h0U-IwceVPm0CCGGW-Vl0saAqZT8P8HAQ Sent from my iPhone using Tapatalk

I'm getting 14.5 mpg now... and my "lean condition" code came back right at the 100 mile mark.. Okay so now I am going to repeat the mileage test using cruise control. I think I may be laying on the gas heavier since the exhaust isn't blaring loud. The loud exhaust may have been an aid in operator control since I was doing everything possible to drive as quietly as possible, and cruise control was by far better than me at giving it the least amount of gas possible per mph. Also I had a full size floor jack, two big jack stands, and my 100# toolbox in the back for the last 100 miles. After that, if I still have junk mpg, I am going to unplug the bank 1&2 o2 sensor 2's. If my 19mpg returns then I may leave it in this condition. Before I leave it with bank 1&2 o2 sensor 2's deleted, I am going to find the source of the lean code and fix it.. Maybe I'll try to find the source of the lean code first... I don't know. My wife's vehicle has it's power steering high pressure hose leaking like a sieve. Sent from my iPhone using Tapatalk

So it is possible... as I am researching the subject it looks like, to a point, running lean can dramatically increase engine efficiency. Combustion temperature does increase quite a bit and more nox is created but efficiency is definitely increased. I am not going to do this but I won't lie, I am tempted to take it all back out, gut the pre and main cats, delete bank 1&2 o2 sensor 2's(replace with resistor), and install a fine adjustment globe valve to purposely get it running lean... 19 miles per gallon is tempting. It really is.. Sent from my iPhone using Tapatalk

No more cel and she is quiet as a mouse again! Initial impression regarding mpg is that I am not getting great mileage now that I've got everything back together.. I am at 44 miles of 100 and the needle is in the same position it was at 60-65 miles yesterday. Is it possible that a vacuum leak was causing me to have better gas mileage?!? Sent from my iPhone using Tapatalk

Thank you guys. I am going to make repairs tomorrow afternoon. This is a great forum, thanks again. Just to gloat.. I mean note, just to note, I am getting 19- yes, you read that right, 19 miles to the gallon!!! My wife's vehicle stays on full 100 years after a fill up and when comparing usages through the week I always feel like mine gets terrible gas mileage but I'm actually getting 4 miles a gallon better!

So that hose is going directly into the back side of the intake manifold and the hose, in addition to being sucked flat, has a big hole where air may be pulled in to the intake. Sooooo might this hose have gotten way too hot from poor timing? The timing belt was so loose when I changed it that I could pull it off without adjusting the tensioner.

Pre cats too? Or only the main cats? Sent from my iPhone using Tapatalk

I don't have access to an obd2 reader. I have just about decided to buy one of the Bluetooth ones from Amazon... But wouldn't a rich condition cause the cats to disintegrate, ultimately causing a clog in the exhaust and a lean code at o2 sensor 2? I don't think air can get to the actual wire from the top of it being cracked. I'm going to silicone it lightly for now. Sent from my iPhone using Tapatalk

So I found this collapsed hose.. I believe it's the EGR?? Might this be the cause of my lean code? Sent from my iPhone using Tapatalk

I thought this might be a lonely road.. So I am in the process of repairing all the broken bolts before I reinstall everything. I just don't know what to do.. the pre cats are glowing about the same on both the driver and passenger.. I would like to just replace them but the pre cats are 3-4 times more expensive and I just don't have the money.. plus they appear to be in OK condition. I want to remove them to have a look see at the engine side since that would be where the clogging would be, but the bolts are impossible to get to with the heat shield on and I'm afraid I won't be able to get the heat shield back on once I get it off and that will leave me in a worse condition than when I started. Today I noticed that the top of my MAF sensor is cracked. If turbulent air is making its way in to the MAF from the road or radiator fan then maybe this was the source of all my woes. Anyone ever see Catalytic System Too Lean because of a MAF? Sent from my iPhone using Tapatalk

Khrrrmm... so I have been seeing poor gas mileage since acquiring my QX4 and my only check engine code has been for misfires. I replaced my spark plugs, wires, dist cap, and rotor which sent the misfire code packing. Now I have a catalytic converter system too lean code. Naturally I ripped off everything from the pre cats back. So after inspecting the main cats it appears they are okay. I couldn't figure out a way to inspect the engine side of the pre cats so I went for a spin and got them nice and hot. Here are pictures of the glow pattern: Driver side Passenger side I am running with both o2 bank 1&2 sensor 2's disconnected. With just pre cats I am no longer experiencing an issue where the vehicle hesitates between 2-3k rpm, opening up beyond 3k rpm. I now have smooth power thru the upper rpm, smooth and loud as crap. I have been reading that gutting the pre cats is fine as long as the main cats are not gutted; the nox is still taken care of and emissions won't be a problem. Nissan, along with many other manufacturers, sought to obtain ULEV status by using pre cats but for the most part they are unnecessary and cause problems being so close to the exhaust manifold. I am sort of at a loss here. I don't know what to do.. I am wondering, can a failing o2 sensor 2 give a false lean code? Has anyone gutted the pre cats? Has anyone replaced the pre cats?

Here are Dicks Creek and Helton Creek updated for better quality. Helton Creek https://justjunk000.wistia.com/medias/kizvmt58dz Dicks Creek https://justjunk000.wistia.com/medias/ltby08oh7z Sent from my iPhone using Tapatalk

Most of it is state wildlife management areas. When I first got my jr50, I searched "north georgia jeep trails" and found Dicks Creek and Charlie's Creek. I then began searching for secluded water falls in my area on google which naturally include trails and beautiful drives. My not so successful endeavors have included trails found from space with google earth. I have found a few really great spots with google earth but the vast majority are locked up/private land.. My trucks suspension needs help. Struts, shocks, springs, and a plethora of bushings have to be replaced. Until I get that all taken care of I'll have to stay closer to home. Luckily there are some phenomenal spots inside city limits and also a few just a hop away! Sent from my iPhone using Tapatalk

We are in the same boat. Please let us know when you figure out the source of your misfires. I replaced plugs, wires, distributor cap, and rotor trying to get rid of mine. I can't tell mine is running rough at all. I can only tell when I take my foot off the brake and the vehicle begins to roll, and as it is rolling from the little bit of power the engine at idle gives to the wheels, I can feel it missing. Maybe it's the whole distributor? I watched a thing about a Nissan Quest, which apparently has our same distributor, and the failing bearings inside were the cause of his troubles.

Here is our trip to Charlies Creek in Hiawassee Georgia. It was beautiful and a little bit more challenging. When I say challenging I mean that a minivan would have to choose its lines wisely https://justjunk000.wistia.com/medias/nuxjsya57a A good free video host is hard to come by...

You have them installed yet? Sent from my iPhone using Tapatalk

An iPhone 6 and a windshield mount made out of a coat hanger and a suction cup. I am working on getting something better and i really want to make a mount to go on the outside of the windshield. I am thinking about a gopro also.

Here is our trip to Helton Creek Falls in Union County Georgia. We had a blast and it was cold!! The road leading to the falls was traversable in a Honda Civic.. but it was beautiful. There looked to be a plethora of awesome creekside campsites that are only accessible by a steep hike. I am the type of person who likes seclusion and ruggedness so the trips we've made so far don't fit the mold. I do appreciate the lack of danger having my babies with me though. The most secluded and rugged spot I know of is actually just outside of my city's limits. Maybe this weekend we will go there. https://vimeo.com/202976867 Next video will be of this past weekend at Charlie's Creek and Denton Branch Falls, ridiculously beautiful!

Yeah +1 for throttle body cleaning. Mystery Oil is good for slowly cleaning deposits and freeing up components gently. Good stuff and I've not personally heard of any negatives, besides the extra $'s. Sent from my iPhone using Tapatalk
