idle air valve?

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.

The n/a V6 will have an Idle Speed Control Stepper motor.

They are known for exhibiting issues and sticking, and/or burning out the coils so they don't work properly.

Firstly, if you've still got the engine management light, you'll want to retrieve the fault codes: https://www.clubvr4.com/forum/showth...agnostic-Codes

The next best thing you can do is to do some logging of what's going on with a piece of software called "EvoScan" - the software and cable needed to do this can cost you under £30, and you will be able to perform lots of troubleshooting with this. This will also help you determine whether the TPS is working correctly.

Do this before spending any more money :)
