I have a 1985 crawler with a 22re that I swallowed the headlights with a few weeks ago with water and drove about 150km with water in the oil. I was lucky cause there is no rod knock and I have done about 3 oil changes, changed my tps, new distributor cap, new plugs. It will start up at cold and idles very rough, no substantial backfires but the engine shakes pretty good and when I pull on the throttle cable it will even out for a second but usually it doesn't rev too high before it cuts out and actually had back pressure out my cold air intake. I have no egr and a pretty basic setup all around. What else could it be any ideas?

im thinking maf sensor?
timing?

thank you in advance!

also i ran a code 7 (tps or ecu) and that was it, even though its a new tps.

 

Compression test. Look inside the intake/air filter housing for oil buildup.

 

Have you pulled the plugs? I'm gonna guess you've got a dead miss/ cylinder not firing. With the motor running, pull the plug wires off the spark plugs one at a time and see if Rpms drop. If they do, that cylinder is okay. If you find one that the rpms dont change, that's your culprit. Good luck.

 

pulled the plugs again and the brand new plugs are all black and covered in carbon deposit but all have even distinction which leads me to believe that compression will be fine. I pulled the air filter and it was clean and dry, I stuck my finger in the afm flap and it was all dry as well. I'll do a compression test tonight once i get my hands on a gauge. this is really starting to drive me crazy.

 

The ECU`S really don`t like water if it was below the water level .

Maybe you can fine a loaner to to try and see if that fixes your issue.

Have you changed your soaked air cleaner element??? Or is the air intake and filter way above the water line

ECU is seeing way more air then your getting so the injector pulse is longer dumping to much fuel hence the black plugs

 

ran another compression test after i had the vehicle fully boosted, they pushed 140psi each so they are good, tried starting it with my air flow meter lid off and i saw sparks. going to try maf and than computer now, thanks for the help this has been a nightmare.
