I get 9 codes for misfires and random misfires, What I have checked and replaced: checked for vacuum leaks and replaced related tees and fittings, I have sprayed carb cleaner at and round hoses and tees with no change in engine rpm, replaced with new plugs and coils, checked all connections for corrosion, sprayed with contact cleaned, cleaned MAF, unplugged the maf while running with no change, the engine starts and runs every-time however has a constant random misfire mostly while idling however when I bring the rpm up to approx. 3000 rpm it seams better but searches when I hold the throttle in one position. I have done the wire check such as wiggle while the engine is running with no apparent change, I've done so much that I forget what I've checked already. Any ideas?
have the same problem?
