I have a 92 integra with a b20b block b16a head.. it had a generic chipped p28 in it and it ran fine... i put a stock p72 in it from my friends gsr... it wouldnt barely start it would die if you didnt give it gas and white smoke from the exhaust... so i put my p28 back in and now its doing the same ****... i reset the ecu buy pulling the plug out for a while, but still with the ecu that use to run my engine fine it wont even run unless you give it gas and white smoke from the exhaust... cels are on too... please help!!!

There is a small plug that needs to be jumped(put a paper clip in it) on the passenger side (about where the passengers right calf would be). Once you jump it turn on the key and count how may times the CEL flashes. cross reference the flashes w/ a code chart(search on here for a code chart). LMK what you come up with.

 

what i dont understand is why when i put the ecu that use to run my car fine in it wont work? could putting the p72 in for that little amount of time dmg something?

 

ok from what i can tell i think its code 21.. vtec solenoid or something?? any ideas on what to do from here? ill search
