1995 Camry 2.2 4cyl 165,000 miles FED (not CA).
Two days ago while doing a routine oil change I noticed my kids engine compartment was real dirty as we had alot of flooding from rain a few weeks ago. I sprayed the engine with a water hose w/nozzle to clean it. DOH!, at the time I didn’t know any better. The car was driven without any issue briefly that day. The following morning the car was driven a distance of 25 miles without incident.
After resting 30 minutes the car was started and began to idle rough and stalled repeatedly. When I showed up to inspect the issue it had been sitting about an hour. I went for a test drive and the car ran good. About 20 minutes later iI get another call saying the car is doing it again. It was sputtering/ hesitating when I attempted to accelerate it began to stall unless I limped it along staying off the gas.
Once I got it home I started doing some research and discovered that my spraying water in the engine compartment was probably what caused the issues I was experiencing. So I began to go through the motions trying to repair. I also noticed the car ran good when cold but at operating temp it would run rough. The check engine light has not come on.
I replaced the spark plugs, plug wires, distributor cap & rotor, ect sensor, and air filter, I cleaned the throttle body port and IAC valve port with sea foam cleaner. I cleaned and tested the EGR valve & ports. Nothing has improved from my efforts.
I must of screwed something up good, since its been 2 days, it should be dry by now. I also been thinking that maybe some water got to the injectors. NOt sure if a cause, but the oil was changed right before I sprayed engine.
My course of action as of right now is.
1.Check and clean all electrical connectors
2.Replace distributor with a re-manufactured one $150ish ugh
3.Replace upstream o2 sensor $50ish
I sincerely appreciate any advice. Thank you in advance.
