82 245 GL. Ok I have posted about this many times and I still can't figure it out. Rough idle otherwise the car runs good all other times. I have had a bunch of work done to this car and im not gonna go into the details but today I got a compression test done and the results were from the 1st to the last cylinder 150, 155, 155,160. So no burnt valve's but now thats one more thing to mark off of the list. Now that proves to be a dead end so im going to replace every vaccumm line that I can see, then lastly comes the throttle body.

Things that have been done to this car.

New injectors, seals, o2 sensor, idle set, fuel air mixture set, flame trap and assembly replaced, tune ups, timing check and set, compression check, and I sprayed WD-40 on the injector seal and the intake with no result.

Note this car does not have an AMM.

What I need is detailed info on checking all of the pins on the ECU for various problems. Thanks everybody for bearing with me on this long journey down the road that will hopefully lead to a smooth running car.
