The compresson test was the first thing I did after I cleaned the cats out Cause thats what I was thinking also. All cylinders had good compression going by my haynes manuel. A mechanic friend of mine also checked the compression just to make sure and He said it was perfect. It runs like its out of time but its not. All plugs have a black carbon look to them and if you let it idle for a couple of minutes it will foul out the plugs. Also white smoke is coming from the exhaust. I've changed the entire distributor including CMP sensor, the fuel injector pack, Crank sensor, MAP sensor, ECT sensor, Coil mod driver, the coil, all plugs and wires, The computer, fuel filter, checked fuel pressure(60psi), Pulled timing cover to check out, checked vacuum lines, checked resistance on all sensor wires, checked and cleaned all grounds.It idles rough, the tach jumpsall around the 1000 rpm area and it backfires loudly, one after another.
