1992 Honda Accord Engine Runs Rich When Engine Temp is Normal
Just a quick question on ’92 accord w/2.2, and something that’s a real brain teaser. after about 10-20 min or running when engine reaches full operating temp engine seems to run approx. 500 rpm higher/richer, with nothing else showing fault or error codes. although, pulling the ECU reset fixes it temporarily, but symptom returns. i hope with your years of honda service and expertise you have seen this very same thing, any idea?? thanks for your time. Thanks, Raf
