I just did a mini me swap. It idels good when the rpm's are kept low but when the rpm's are brought high and I come to a stop it almost wants to stall and some times does. The car drives great but just when I come to a stop it idels bad. What can this be???????????? Oh ya and the timing is perfect.

nobody knows why?

 

i just did a mini me swap and we had the same problem. I would check the voltage on the TPS. Cause like a said in other post you will not get a CEL if the voltage is too low. Also check for a vaccum leak. both were my problem!!
