Check Engine Light Problem

[Cgillies86]

My check engine light is never on when I am driving ,however, when I come to a complete stop while in nuetral the check engine light comes on. But if I push in the clutch the light goes away. Other times if I just tap the gas it will go away. It is kinda weird but I would like to know if anyone else has had poblems like this. I have a fidanza flywheel, I don't know if that is causing it?

Go read out the CEL codes. Also check the battery voltage when idling and the light comes on to see if you have an alternator charging problem.

Yes, check the CEL codes.

My battery terminal was loose one time, it had starting problems. tightened up the battery cable. problem went away.

Check the ECU Error codes, and also check the connections on your injectors/coil pack/PTM. If one of them is shaking an getting an intermittent connection you'll get a cylinder misfire code. The flywheel isn't causing the CEL, and a weak battery connection isn't causing it either.

I connected my logger and it said my throttle point sensor was bad, anyone know if this could be it?

Sure, the TPS may be worn out or misadjusted.
Log it and make sure that it's about 10% at idle and that the output is smooth with no spikes or dropouts as you go through the range of throttle positions.

So if one of the injector clips was broken off one side, it could cause it to throw a code because of vibration?

He was trying to help you troubleshoot it BEFORE you datalogged it and found out what the problem is.

It's the TPS!
