96Pathfinder4x4 Posted January 10, 2013 Author Share Posted January 10, 2013 After putting everything back together, I have the same problem: No vacuum TO the EGR via the EGRC-BPT & Vacuum solenoid. I also have a variation at idle...basically like someone is tapping on the gas pedal. I run injector cleaner every 5-10k. Chevron Techron stuff that comes in a case at Costco. I don't think the diverter would be a problem, unless I was getting vacuum to the EGR. I'm going to suck it up and drop it off at the mechanic tomorrow. At least this way, the problem will be fixed and I will be insured to pass smog. Link to comment Share on other sites More sharing options...
ejin4499 Posted January 11, 2013 Share Posted January 11, 2013 (edited) Id bet you dollars to dounuts that if you checked your sensors and they work properly you have a vacuum leak somewhere on that engine. Thats what is causeing the idle to jump like someone tapping on the gas. If you have a big enough leak to cause your idle to jump your egr is the smaller of your problems. I would find the leak before I sent it in to the mechanic. Also did you by chance have your wiring harness completely disconected at any time in the past. I think the connector for the IAAC valve fits the vacuum solenoid you may have gotten them swapped. Edited January 11, 2013 by ejin4499 Link to comment Share on other sites More sharing options...
Precise1 Posted January 11, 2013 Share Posted January 11, 2013 Don't feel bad about it, you have done a lot of checking and testing to determine what the issue is so the mechanic shouldn't have much trouble taking it from there. As a fellow Californian, I know what it is like to deal with smog requirements and the timing of it all. Let us know that the find/fix is, please, and good luck.

96Pathfinder4x4 Posted February 3, 2013 Author Share Posted February 3, 2013 Update: So far, not fixed. Due to my troubleshooting, I set the MAF sensor code. Apparently after clearing any code that has to do with emissions, you have to wait for the cycle to run. I've put 230 miles on it and it still is not ready for smog.

Towncivilian Posted February 3, 2013 Share Posted February 3, 2013 Drive on the highway for 20 miles if you haven't yet, it might help the cycle complete. Link to comment Share on other sites More sharing options...
96Pathfinder4x4 Posted February 3, 2013 Author Share Posted February 3, 2013 I have. I drove out to the desert last Monday. Stop and go, car on and off, speeds up to 70mph., etc.... On a good note, I learned that my code reader can tell me when it's ready...so I don't waste time getting a ride to the shop. Link to comment Share on other sites More sharing options...
96Pathfinder4x4 Posted February 3, 2013 Author Share Posted February 3, 2013 I plan to take it everywhere I can.... Reg expired last month. Link to comment Share on other sites More sharing options...
sewebster Posted February 4, 2013 Share Posted February 4, 2013 Probably obvious, but when my EGR wasn't working the reason turned out to be that I had the vacuum line hooked up to the wrong place. There are a bunch of little tubes over there that are basically the same... but presumably you've though of that Link to comment Share on other sites More sharing options...

96Pathfinder4x4 Posted February 9, 2013 Author Share Posted February 9, 2013 I've put over 300 miles on it and it's still not ready to be smogged. The most recent was 28 miles to work...each way, all freeway. I have no idea.... Link to comment Share on other sites More sharing options...
96Pathfinder4x4 Posted March 1, 2013 Author Share Posted March 1, 2013 To update, after about 600 miles, it was finally ready and PASSED! So, basically my mechanic set the timing back a bit (within specs, of course). Next...bigger tires! Link to comment Share on other sites More sharing options...
