Engine Performance problem
1989 Honda Civic 4 cyl Two Wheel Drive Manual
Car starts and idles fine. Timing is on the money. Plugs are a light tan. Fire to each plug. I rebuilt the motor and it has roughly 40,000 give or take. The fuel filter, O2, pcv, and fuel pump have been replaced during or after rebuild. After the car reaches operating temp, not necessarily when the fans kick on just what the temp gauge normally reads, it acts like its missing. Its worse if trying to drive it. I replace the IACV with one from a junk yard with no luck. It will not show a fault code. I also Ohms checked the TPS and it seems to be working fine. I also replaced the igniter. It seems like a sensor is affecting it only in open loop. I'm not an idiot when it comes to vehicles but I'm at my ends wit trying to figure this one out.
have the same problem?
