I duno,, After I took the filter out, I blew through it and it seemd to flow fine.. I am thinking maybe I had water in the fuel.

I can live with 17mpg. I have not been easy on it either, just driving to work and back, only twice on the interstate. I hope to get 20mpg out of it on the highway, its just a winter vehicle and camping machine. Yeah I had to get on it around the corner so it kicked down and locked up, countersteered and pushed right through the corner in the wet, much better then the open diff. I got it at NAPA, I think I might have gotten a one time good deal... Not 100% sure how it worked, but they charged me 40$ plus tax for the caliper and 80$ for the core! So leaving NAPA I paid them 120$ plus tax (cant remember exactly), and when I came back, I got 94$ back for my old caliper core. I was a happy camper. Just got some Satisfied Metalazer rear brake pads in the mail today (10$ plus shipping) originally 60$ pads...! I seem to be finding the deals lately :-) Slowly getting together everything to do all the brakes, new pads/rotors. I was going to go with Brembo rotors, I figure before I do, if anyone knows a better brand?

Ever since I replaced the fuel filter it seems to be running fine... Strange... Maybe it was bad gas?

Well to update.... Since the weather has been colder it runs fine... Very strange. Even after I shut it off and start it up (when its still warm) it runs fine. I have had it miss after just starting up and its still cold, just a random miss every 5 seconds or so under idle only. After I drive it it goes away. I put my stereo in it, and.... well, I am still trying to figure out the whole factory amp thing... its kind of retarded...

I went to the parts store and bought a brand new caliper for 40$, the caliper I had was done, the inside was all gross when I took it apart, the fluid had dirt in it and it was like sludge. I replaced it and its great now! I pulled the ABS light bulb out so its not so annoying at night :-) She is running great. Im getting about 17mpg. Is that good for a motor with 111k on it? Im not being easy on it, it rained yesterday and took it on the onramp to the freeway to see how well the stock LSD works. Locked up nice, good stability around a corner :-)

When I took off the caliper, the slide pins looked great, all lubed up and came off and went back on with no issues. The piston was packed full of mud and is rusty on the inside... I am going to go search for a rebuild kit and see what I can do. Thanks for all the advice thus far... Im getting tired of working on it so I told myself I would relax this weekend and save it for Monday. Will post up results as soon as I get to tearing it apart :-)

Well after taking apart the rear break that was sticking and adjusting the e-brake (I couldnt even budge the rotor to take it off the Ebrake was so tight) I cleaned everything and put it all back together and the caliper seems to be sticking still... Anyone have this issue? Do the rear calipers have issues I should know about? What is the easiest way to fix my problem, buy a new caliper or rebuild kit? Or is there a way to break free the sticky caliper so it works again? I am going to try pushing the piston in all the way, and then put it back together and see if it sticks still.

Cool, thanks for letting me know what it does. I can live without ABS, I just have to unplug the light in my dash so its not so annoying... I think whenever I take the rear end out again I will just swap the covers, or just pick up another rear with LSD and ABS... They are not very expensive anyhow.. When I looked at the brakes today I found that it wasnt the caliper that was dragging, it was the ebrake shoes, my drivers side was almost locked up! Made it nice and hot on the drive home from work today... Anyway, I took it all apart and cleaned it up with brake cleaner, lots of mud and dust in there. Going to assemble everything tomorrow and see if it solves my problem. If so, I will have a good running daily driver! At least for now... :-)

I have a 91, XE, 4 wheel drive, automatic, no power options, AC, and ABS. Bought a 95 front and rear diff with LSD, disk brakes, and 4.6 gears. The brake master that I had was leaking, so I bought a new one, and I got the one for 4 wheel disk brakes since I was upgrading to rear disk brakes. NON ABS ( I didn’t think I had ABS). When I was removing the rear end, I noticed a sensor in the input shaft of the differential :-\ Installed the new rear end and it doesn’t have the provision for that sensor. I installed the new master cylinder and bled the brakes, took it for a test drive. The ABS light came on (I didn’t know I had ABS until then), I tested out the brakes, 25mph sudden stop, 60mph sudden stop, and 45mph made sure they all lock up if I slam on the brakes. Everything works fine except the rear disks are dragging a little (muddy and a little rusty), so im going to take them apart and clean/grease them today to see if they are just sticking. The rotors and pads will be replaced soon. What is the difference between a ABS and non ABS master cylinder? What does the sensor in the rear end do? (also what is it called?) Do I need to swap input shaft covers in order to retain that sensor? What is the easiest way to deal with all this?

Well after checking things out, the temp sensor is fine. I checked the ECU and did Modes 1-2 and 3. Mode 1 had no issues. I believe it was mode 2 (mixture) was fine, and Mode 3 tells you if sensors are bad or malfunctioning (this is where it would tell me if my temp sensor was not working). Well the code it gave me was 12 (Mass airflow sensor). Im thinking that would be a good reason for it dumping fuel and missing randomly. Is there a way to test the MAF before I replace it?

Ok

75$?! I bought one for 35$, and it came with a new plug and everything... Im going to replace it this weekend and see if it helps anything. But the sensor is from the new motor, same problem, different sensor? I will have to try to unplug the sensor and see if it makes a difference in how it runs. Thanks for all the tips, ill post up some results after the weekend when I get a chance to work on it.

Well its not the MAF sensor, it did it again today, and I played with it, nothing changed. I drove it 20 miles, let it sit for 10min, and went to pull it in the shop and it ran like crap, randomly missing and sputtering. After limping it in the shop I unloaded the rear end I plan on installing soon, and let it sit for about an hour. It cooled off, I started it up to go home, and it ran fine all the way home. Im going to buy a new oxygen sensor tomorrow and install it over the weekend, along with a new brake master cyl, and 4.6 rear end with disk brakes.. If I cant narrow down the issue by replacing common parts I am going to take it in and get it diagnosed.

I will try that again. I tried that when the old motor was doing this, and it didnt fix the problem. If the MAF sensor is broken, it will not work, correct? Or can it be broken and work off and on?

It is not a limitation in RPM. It is randomly missing so bad that it wont go past 4k under WOT. The throttle cables are fine, nothing wrong there. It idles fine at 750RPM, and drops to about 700RPM when at idle when it misses. Under any throttle, it jumps all over the place... I have not checked the codes yet, I will try to unplug the O2 sensor, and see if thats the issue. I am not getting a CEL yet. I started it up again today, and drove it around the block, it ran fine... Its mind boggling... I have never had this problem with a vehicle that I could not diagnose.
