302 V8 EFI issues
Hey guys!
I'm helping out a friend that has a 1989 302 V8 with the EFI. It's run perfectly for years, and has now suddenly stopped idling properly. Up until yesterday, I could start the engine cold and it would start right up on fast idle, then slow down after a few seconds. Nothing has been replaced, or changed.
It's got new plugs, wires, distributor cap and rotor. All I know about the EFI is to check for vacuum leaks, which I've found none. A few months ago, we replaced the throttle position sensor.
Got any ideas? We've run a bottle of GumOut into it. There's no water in the gas. I took it out and blew out the engine on the interstate. Runs great at highway speeds, but no idle.
Thank you in advance!
