ECT/ACT Chart
If the stalling issue didnt occur until you got the engine wet,moisture probably got into an ignition component and caused it to stall.Under the distributer cap,tfi harness,coil harness,coil wire,etc.Does it restart easily after stalling or does it present with a hard start or no start after the initial stall??
If stalling was present before engine cleaning,check these things:If the stalling issue didnt occur until you got the engine wet,moisture probably got into an ignition component and caused it to stall.Under the distributer cap,tfi harness,coil harness,coil wire,etc.Does it restart easily after stalling or does it present with a hard start or no start after the initial stall??
The iac valve- its used to control idle and its opening/closing is dependent on coolant temp.The valve is opened fully when the engine is cold and closes as the engine warms up.If the ect sensor is defective,telling the computer the engine is warmer than its actual temp,the iac valve might open fully at startup,but it'll close much sooner than normal due to the elevated coolant temp.The ect sensor can be tested by disconnecting its harness,placing ohmmeter leads across both sensor terminals and taking a reading.Do this while the engines cold then warm the engine up to operating temp and do the test again.Your ohm readings should match the chart below.
The most common causes of intermittent stalling are a defective pip sensor,tfi module and ignition switch.
Check the eec ground really well too.Its located on the driver side fender apron near the windshield washer reservoir.Make sure its tight and corrosion free.The eec ground also has a tubular plug that connects to a matching plug.Unplug this,spray electrical cleaner into both plugs and scrape any corrosion off the male and female terminals.This ground will cause stalling if its loose or corroded.If it becomes disconnected,
the fuel pump will run when the key is in the start position,but it'll stop running once you release the key to the run position.
