Car drives great but for some reason, it just won't idle after it's warmed up. I have to press on the gas just to keep it alive.

The wierd thing is when it does die, I go to start it up and the idle goes up to 1500 and stays there. I know it has something to do with programming so can someone help me out

Is there a way I can turn up the idle at a certain temp. Or should I change the a/f ratio at a certain temp and see how that does.

 

You could be having a problem with your temp sensor in the water pump. Have a scanner to monitor it?

 

Is this a DFI setup? IF so check for something like coolant temp change to AFR.. I would bet that its getting to rich..

Remeber rich cars idle low and rough, lean high and surgey

 

I think I may have found the problem. I'm thinking it might have something to do with close loop. I have close loop enable from 33-60 celcius. Once it gets out of 33-60 range, it starts reading from my O2's. That's probably why my wide band is reading so damn lean. I'm going to try changing the settings to 33-130 and see if that changes anything.
