It is backfiruing and sometimes stalling.
I have put new cap and rotor, plugs/wires, EGR valve and solenoid, cat, O2 sensor, Maf sensor, coil, fuel pump, fuel filter.
I had inadvertantly tried to start the truck while I had the jumper in to check trouble codes.
What is the liklihood of me damaging the ecm by doing so?
Is there a way for me to test the ecm or do I have to have it check at a dealer or repair shop?
I do not want to spend another 100.00 on an ecm just to find out that is not the problem.
have the same problem?
