I cleaned my engine 6 days ago with simple green and then pressure washed. I noticed that my battery died in the process, so I charged it and it started and ran the engine for 5 min. The following day, I wanted to see if my battery would hold charge and it started but required high RPM (>1000) to maintain the engine from stalling and I could smell the gas from the exhaust. I ran for codes and it displayed P1126, which was magnetic clutch malfunction/short and I then began troubleshooting. I checked the resistance in the APS, TPS, magnetic clutch and motor resistance as per manual and everything was within spec. With the ignition on, I could see the throttle valve move with me pressing on the accelerator. For good measure, I cleaned the perimeter of the throttle body with a cleaner and rag and also cleaned the MAF sensor. Still it didn't idle correctly, so I took out all of the coils and found cylinder 1 and 3 to have some water around it. I used a air compressor and dried the coils as well as blew out the water polling in the engine. Only found water in cylinder 3, but then removed the spark plugs in 1, 3, and 2 and the plugs looked ok. I put back the coils, plugs and intake and hoped that it would all work but it still was rough idling. I ran for codes and now, it is P0300, P0301, P0303, P0308. Random misfiring. I am concerned that the water could have affected the many electrical connectors in the engine bay. I looked over the camshaft position and crankshaft sensor for retained water, but it seemed dry. I then cleaned every electrical connector with a cleaner and put dielectric grease in the connector.
I am so sorry for the long post but it was the only way that I could describe my thought process and troubleshooting. I just bought the running car last week and I wanted to clean the engine bay thoroughly, to look for gasket leaks and the power steering leak. I have no real experience troubleshooting cars and thought that the experts in the forum might be able to lead me down the right path.
what should I do next? replace the coils in 1,3, 8? I just purchase the techstream cable, will this help me troubleshoot and how do I use it?
thanks for any input!
