How many miles? Do you drive it hard?

Check spark plugs, fuel injectors.

Clean your engine lately?Water down in the spark plug holes will cause symptoms like you are describing.

If you just changed your plugs, go over your work again. Maybe a spark plug wire has gone bad, or come loose.

Do you mean you are throwing code 0301? If so, you might want to get another ECU.

0301 ECM control unit The ECM input signal is beyond “normal” range

i grounded all of my spark plug wires before replacing them and found out that they were misfiring so.. i replaced them and bought all new ignitior components, minus the coil and.. it fixed the problem.

well so far i have checked my wires changed the distro cap and checked basics is it hard to remove injectors how could i check them?
