throttle issues after cleaning engine
Yesterday I decided to clean my engine because it pretty oily and gunked up with dirt. I covered the alternator with a plastic bag and then went to town with some Simple Green. After quite a few sprayings, I closed the hood and let it sit for about 10 min and then sprayed it down with a garden hose.
It sat for about 4 hours before I started it up and tried to go somewhere but I couldn't get any farther than my own driveway. It would idle and go into gear, but I had no throttle response and could only move under idle power. I could put the gas to the floor and nothing would happen.
I let it sit overnight hoping that it would dry out and fix the problem, but it only sorta helped. It was idling rough with the rpms fluctuating. I could drive, but throttle would only kick in with the pedal half to the floor and then I would take off like a rocket. I couldn't do any smooth acceleration.
I'm wondering if I got the PCM or some other electrical part a little too wet. Any ideas?
