Pontiac Grand Am Repair Question
Accelerates itself
Answer
You need to find the codes in the computer for starters. As the engine is getting hotter it may be opening up a vacuum leak wider. The shop you had it at gave up too easy.
You don't need the dealer unless you want to go there. Often times you'' get better diagnosis from independents. IF you need help finding one, let me know what city you're in.
The exact words from the guy I talked to was "the computer is messed up and its probably because of water damage" I just found the receipt from the place and it says the rean a diagnostic test and the PCM was bad and it was probably damaged from the water. I don't doubt their ability but I find it odd that it would malfunction nearly 2 weeks after being in water. Also where is the PCM located because I'm not sure the water went high enough to damage it.
I'm located in Saint Albans, WV (outside of Charleston)

I have found that the shops that belong to the IATN network are generally more savvy. I don't know any of these shops, but believe they have an edge on most others.
Call and talk to them, make an appointment with the one that sounds best to you.
