92 DA w/b20, having issues...

[teglover805]

I purchased a 92 DA with a b20 swap last week and have noticed that after warm up or a 15 minutes of driving the check engine light comes on. Also the idle, during warm up, is 1500rpm's. However, during normal driving, I'll come to a stop and the idle will be at 1200rpm's OR they will jump between 600-900rpm's. What's up with this? Is it the ECU, or possibly the distributor? I'm at a loss as to what the problem is. All HELPfull answer's are appreciated !

check and see what code or codes come up on the ecu. if you have a CEL, you will have a code. that will tell you where to start looking. look in the reference section on this site, everything you need to know about CELs.

it is more than likely a problem with the IACV, or possibly he FITV if i had to guess.

Thanks for the info mdpsEG. I'll have to do it this weekend and then post the codes I came up with.
