WELL I FINALLY figured out what is wrong, but can't figure the cause. The engine has been idling very erratic: loping, high idle to REALLY lo idle, misfire, and dying also ALOT OF SMOKE!! It sounds like alternate cylinders are firing at random. They turn off and on then off again. Once in awhile ALL 8 will fire and it'll run VERY smooth with little smoke and engine vibration. This has been the problem since I first got it. Is it possible that my CPS (grey) is the cause? I have checked ALL sensor connectors and they are clean with all the proper voltages. This dying (can't get out of driveway) really started AFTER I replaced an O-rings on the oil rail. It was dying b4 but would restart and no further problems; however today would not stay running.
