Hey Guys,
Recently my 2001 Nissan Maxima stalled out and I had it towed to a mechanic. He ran a basic scan and the error that popped up was P0505 (Idle air control motor circuit malfunction). He then went ahead and replaced the IACV. However, after he replaced it, the following things occured:
1) Error code P0505 still shows up.
2) SES light on (never was previously)
3) High RPMs (in P and N, it's between 2,000 and 2,500)....also, after the engine is warming for a bit, the RPMs jump back and forth rapidly between 2,000 and 2,500
4) When in drive, the RPMs settle around 1,000 but sometimes jump up ever so slightly when driving.
5) While driving and the RPMs hit around 2,000 there is hard shifting/bucking.
6) When I apply the break to come to a stop, it almost feels like it doesn't break quick enough and it seems like I have to put my foot completely down on the break.
7) When I come to a stop it again shifts/bucks hard before it comes to a stop.
8) Mileage seems to poor (more than usual).
My main concerns are:
* Is it OK to drive like this for now (2 mechanics I've talked to said it is)?
* What could be the cause/problem? I've looked on these forums and elsewhere and I have seen anything from cleaning the throttle, to replacing coils, to changing the MAF sensor, to leaks, etc. Having seen the symptoms, what could be the cause?
I am going to be bringing the car within the next week to a mechanic who has many specialized computers and diagnostic machines (more than just the regular AutoZone scanners)...but I was just curious what it could be.
Also, as my screen name says, I am a newb and I really know nothing about fixing cars (except for the basic stuff), so any help that you guys could give me would be greatly appreciated.
Thank you very much for reading this.
