1997 f350 7.3l. running good. then slowly would actually choppy. then would clear up. then off idle and stops. slow acceleration would be very choppy and stuttering but clears up higher speeds. Also been harder starting. shows check engine light every now and then. finally got it started and it was misfiring very bad and then died. scanned it. ipr duty cycle shows 15 percent while off and 55 while cranking. icp also shows 2500-3000 psi while cranking.
