Hello, I got an issue. I have a 91 ex that I just waterlogged the motor and slapped in a brand new LKQ engine with a professional. It had a slight idle problem before the motor the rpms would increase or decrease ever so slightly. After the motor the truck will run great cold with no issues and idle like a champ. I can drive 40 to 60 miles with out a problem but as soon as I stop to idle for more then 5 or 10 minutes it will start to stutter and idle rough. IAC, MAF FPR 02 ICM TPS crank sensor has been replaced. No obvious vacuum issues and good fuel pressure. If I idle it for a bit then go drive off the CEL turns off. Its intermittent and extremely frustrating. I work at a shop and my mastertech specializes in classic car restorations and I will be working with him on the issue aswell. Anybody got an ideas? Thank you.
