hey guys, i'm somewhat of a n00b on here, but i definitely am no n00b to cars. car is 92 sc400
i pressure washed my engine bay yesterday (just the edges and by the firewall as best i could) and totally tried to avoid the engine and battery and all went well. then i drove home, which is about 2 miles away, and pulled into my driveway...
the car started randomly misfiring, then it started misfiring more, then more, until it finally stalled..... i started it back up and it was running very rough, misfiring horribly, back firing, and barely running. it's just like after 30 seconds or so after starting the engine cold, the engine starts dropping the ignition signal for some reason.
1. i disconnected all of the injectors and made sure their connectors were dry.
2. i took both distributor caps off and cleaned them because i thought there may have been water in them (there wasn't)
3. i reset the ECU and the car fired up just fine (it had been off for a couple hours at this point) then started doing the misfiring again, kept doing it, it got worse, etc. just like before.
i am thinking maybe i somehow messed up one or both of my ignition coils, or possibly the ECU. the weird thing is that the car runs PERFECTLY smooth for about 30 seconds after it has sat for a while, then starts the random misfiring that progresses into running horribly, stalling, and not wanting to start... CEL is NOT on.
anyone have any ideas?
