1990 Honda CRX Q&A
1990 Honda CRX Question: 88 crx dx engine swap gone bad!
I have an 88 CRX Dx that had we had finally worn the original motor out. A buddy put a 1990 civic dx motor with 70,000 miles on it into my car. I changed everything major but the computer and wireing harness. The car starts and runs but if I hammer down on the gas it will stutter and backfire, then stall out unless I push the clutch in before it dies. they thought the timeing was off so we fixed that issue but it still backfires and dies if you push gas to hard or drive up an incline....even tring to get it up on a car hauler it dies! Im confused and desperate for advise...she was my first car and had her for over 5 years. I want my baby back! Any help is much appreciated. - tipple_1999

Check the computer ground at the thermostat housing. Then see if you swapped the IAC plug with the O2 plug - Visitor
