The car is an automatic V6 w/ only 45000 original miles. It was driven pretty roughly by its previous owners and has been sitting in the garage for almost two years so it could use a tune up. We tried adjusting the TPS but it didn't work. I have read on some forums about the IAC or MAF being the problem and I've also been told it could be a tranny problem. Right I'm just looking for the easiest, least expensive and most effective plan of attack to take and appreciate any ideas! Thanks
