Hi, I'm new. I have an 89 civic that I've started having some misfire issues with. It basically started when the ECU threw a water temperature sensor code. I reset the ECU and the code hasn't come back for about 600 miles, but it started misfiring. It will only misfire once it's completely warmed up, and it will only misfire at low throttle positions (maybe 10%) and it's worse when accelerating. Sometimes the idle is pretty rough too. I cleaned out the IACV (EACV) but it didn't seem to solve the problem. I've also put in a can of Sea-Foam, but it hasn't really fixed it either.

Please help, I'm driving to Nevada next week (2000 miles) and I want the car to make it.

I accidently posted this in the engine forum, I think it belongs here.
