Message I've searched for weeks here and have learned alot about my new Z. I've tried everything suggested and it has helped but I still have 2 problems left and nothing seems to fix them. I couldn't start the car when I first got it and after a few hours of cleaning contacts it started with an erratic idle. I worked that out smooth, yet still get a bouncing idle. It just revs up and down and stalls at every stop. It even jerks in between shifts(TT Auto). I've checked plugs, compression, disassembled and cleaned the AAC, TPS, FICD, injectors, coils, CAS, PTU, MAS, and checked all their resistance. Plus changed the PCVs, temp sensors, cleaned out throttle bodies, adjusted TPS, and cleaned every connector that I can see in the engine bay. I even made that little vacuum tester and found and fixed every leak I had([ http://home.swipnet.se/e-solutions/Vacuumleak.html ]). The only thing I can't remove is the air regulator, but I did check the resistance and found it to be ok. Plus I get 10MPG. Any suggestions? Thanks.
