throttle body

[mailee]

I'm using proton wira 1.5 i (auto). I.m having a problem with the RPM of my car its very especially when I stopped a car and still in gear mode.The fuel pedal sometimes it makes a movement when I released it (can feel it slightly movement). Some of my friends said it due to the throttle body need to be services. Is it because of that ?

2002 could still be VDO or MMC.

I don't quite understand the problem here. Can you describe how to replicate the problem? Also what mods have you don to your car?

it happens very bad during idling when aircond is ON right ? try to service the throttle body using choke cleaner... it will feel better..protons TB having lots of this problem..even same goes to mine.. if still the same,i might encourage u to do some mod using the toyota FICD or honda vacumm so that when aircond were on the idling stays stabil cars feel lighter.smooth acceleration... if not,u can go to half cut and get a ori 2nd TB...

thats right, take off the throttle body and clean it, will be better.
