i have a 1993 dodge d150 with a 318. It will not idle on its own, and the check engine light is on. It will not throw out a code of the self dianostic. When i go to drive, if i floor it, it cuts out and sounds like it backfires then will take off, but if i dont keep my foot on the gas it stalls its self out. I just recently changed plugs and wires
