So my truck started runing rough last thursday thought maybe it was a bad tank of gas or something, cause the engine light wasnt coming on. well it continued throught the weekend. sat night I hooked up my fuel guage to see if it was a fuel issue. was holding at 32psi while idleing and would jump to 40 if I reved the motor. Figured that seamed a little odd so I went ahead and ordered a BBK fuel pressure reg. sunday it was buging me more so went to advanced auto and purchased a scanner and hooked it up and found a code p0385. monday morning I called up my ford dealer and ordered a new crankshaft position sensor. Got it that evening and installed it yesterday. ran great for a good portion of the day. than in hte evening went out and it started acting up again. today hooked up the scanner and it's got a code P0300. I had just done the sixlitre tuneup minus the timing adjustment back in april. put in 8mm wires, msd cap and rotor, autolite plugs, MSD coil (stock replacement), new ignition module from Ford. im not smeling any rotten egg smell from my exhaust......been thinkin about going out and getting some new motorcraft plugs to replace the autolites....any sugestions on where I should go on this? Going to be looking around for a vacum leak next cause a few times it was starting rought it backfired and blew off a vacum hose that connects from the throttle body to a valve that has a line going to the charcoal canister.
