Hey there, just wanted to thank you for your thread on your rough idle probs. Man you went through a lot to get that diagnosed but reading what you did armed me with quite a bit of knowledge and is helping me flesh out my prob Im having with my 99 GTP. Pretty similar issues but I am not very car savvy so Im hoping just replacing the maf will do it. You seemed to be quite familiar with swapping out the plugs. Thats next on my list but its my first time ever and im a bit nervous. Any pointers or recommendations? Im trying to find a good guide but no luck yet. Im not too concerned with the front but the back ones look impossible to get to. Do you recommend any plugs, wires / coils? Im hoping to fix the car up nice to sell it and I wouldnt be able to sleep at night knowing I sold a messed up car to someone. Thanks for the informative thread and all your efforts.
