hi the engine mang light was on when i bought my latest v6 galant, the guy who sold it said it was a problem with the tps, (the car sometimes surges when you are slowing etc) so i replaced the tps and the light didn't do off and the car still surges although not so much i think. Anyway a friend said the other thing it may be is the idle air valve? but when i looked on ebay there were 3 different things that all claimed to be idle air valves for the galant. Could someone post a link to the one i actually might need, that'd be great. My galant is the v6 elegance 2002 thanks David.
