Are these problems related?
When the car is warm it'll idle at 1500 rpms fairly constantly. But recently it has developed a new problem.
When the throttle is about half open or so it'll misfire quite a bit while driving. If I go WOT, the problem goes away and it drives smoothly then.
Also, sometimes at idle it'll drop down to 500 rpms due to misfiring and then it'll climb back up to 1500.
Are these problems related? When I first put the engine in the car I wasn't getting fuel or spark and it turns out the ECU plug was a bit loose. So I really cranked on the bolt on the plug and pushed it in all the way that I could and it fixed it.
