So far, I've replaced the #1 coil, (new plugs while I was there)Compression check too. 150-160 across the board,first bump was to around 100 on all cyls if I remember correctly. I don't have a leakdown tester,something to add to the list. Removed and cleaned the injectors,swapped the #1 and #3 injectors, Checked the signal to the injectors with my noid set. Swapped out the ECM with a remanufactured one that I was promised would not have to have the crankshaft variation cal done with. Surprise, surprise. He lied. Still setting the same ABS code but now can't read misfires, which it is still doing. Reinstall original ECM. Still getting P0301 and c0561 codes and now to make it even more interesting, the doors randomly unlock themselves, even with the battery out of the remote.I'm going to jack the car up and do a close inspection of all the ABS sensors this afternoon but the questions I have are
Is it even possible for the ABS computer to affect the running of the engine, other than "reduced power mode" which I assume would knock back timing and /or scroll through the cylinder deactivation as opposed to setting a single cylinder misfire
Is the Computer above and behind the ECM for the ABS, or is it the BCM.
Has anyone ran into weak or broken valve springs on these motors as a reason for a misfire?
