Hey guys, I have a 01 25th ann special edition maxima..I recently put the car back on the road so it was sitting for a while..before I let it sit the car had a pulsating rpm problem..Threw research I found out that when the iac valve went bad if toasted a chip in the computer..I sent the computer out had it repaired from a service on ebay that repairs them.. Anyway the idle issue was fixed and the car seemed to run ok but I noticed that the slip, Traction control, abs, lights were all on..

After starting it a few times they disappeared so I figured I was in the clear..NOT! The next day on again and it feels like the car is misfiring and running like crap..That same day I started the car they are all off and the car is running like a champ..This has been going on for a few weeks now..\
Car runs great sometimes with no lights except SES light then I start it an hour later all lights are back and the car is running like crap! Any thoughts?

 

When you fixed your "pulsating RPM" problem, did you replace your IACV with an OEM part? If not, did you measure/test its quality in any way?

What company did you use to fix your ECU? (Search this forum for "fix ECU" .... not all these companies are reputable.) How much did you pay?

Even though your SES light is not on, check for any pending codes and report them here, otherwise we can't help you.

 

What he said ^^^ plus you might have a weird problem in having 25th anniversary Maxima, those are known to have problems.

 

Sorry guys I havent been on in a bit....It was a long time ago when I had the comp fixed so I cant really say what company it was...When I had the pulsating problem I replaced everything! Mass air, TPS, IAC, all parts were purchased at advance auto cause my ex wife at the time worked there..Before I put it back on the road I replaced all 4 disc, new pads, new tires, this car should be running like new!

I have the code scanner from Advance auto..I gotta check what codes I get and post back..By the way, THE SES light is on..Its been on..Its extremely weird though that the lights come on and off and all appear to have to do with the wheels except for the SES light, I have the SLIP, Traction control, ABS lights all on.. I drove it today with all the lights on and it ran beautiful..Tomorrow will probably be another story.. This car is hot stuff!

 

To answer yourother questions, No I did not get the IAC from nissan, It was from advance auto and I have no idea how to test it...To fix the comp cost me around 100 bucks
