I have a 2000 Maxima (GXE) and just recently had the IAC valve go and it DID take out the ECM. Today, I get the car back after having both parts replaced and as I'm driving off the lot, I notice the trasmission timing is off. When I step on the accelerator (about half-way to the floor), the car goes through 1st, 2nd, possibly 3rd, but then the tac just revs up to between 4000 and 5000 RPM before the 4th gear / overdrive FINALLY kicks in. When it does kick in, you can feel the bang and car shudders. Mind you, I'm not sure exactly which gear transition this is taking place at. It might be from 2nd to 3rd, it might be 3rd to 4th, etc. - who knows. All I know is that I never had a problem with transmission timing or slow acceleration before the IAC and ECM were replaced and now I do. Any ideas/thoughts on why I suddenly have a transmission shifting problem (i.e., shifting to a higher gear far too late)?
