Still fighting the good fight with no gains.
Still getting the random misfire codes with fuel cut-off.

Last night I removed and cleaned the injectors. I cleaned them with carb cleaner then cleaned them in a ultra sonic cleaner. Rigged up an electrical connector, switch and battery, opened each injector electrically and blow pressurized carb cleaner through them. Reinstalled.

No change. Still getting the codes.

I have ordered a new MAF. Maybe thats it?????

My list of things that I have repaired or replaced and NOT fixed the problem is getting longer. Must mean that I am somewhat closer to the solution.

Again, I appreciate any help or advise offered.
