Well, this weekend something weird happened.
First, the weather. ?Very nice Saturday, about 60-65*F. ?Saturday night, lots and lots of rain. ?Cooler, in the 40's. ?I did some driving in the rain, and there were some large puddles I drove through. ?Sunday morning, in the high 30's, and still raining hard.
I went to fire up the truck Sunday morning here at the g/f's house, in the pouring rain, and I kind of accidentally didn't hold the key on long enough. ?The engine sputtered and died. ?I've done this before. No biggie.
I turn the key again, and the engine turned over for a good 6-8 seconds with nothing but sputters. I let off, and ?I turn it over again. ?I know it's fuel injected and all, but it wasn't going to start so I played with the throttle to get it running.
The truck was only running on 4-5 cylinders (I felt what 6 feels like on an V8 before, and this was not 6!). ?It sounded AWEFULL and would not idle. I had to play with the throttle to keep it running.
I shut it down, and became quite mad. ?My g/f has some problems with mice making temporary residence in her car's engine compartment. ?(Her driveway is near a neighbors horse-barn.) ?I pop the hood expecting to see some fuel injection wires chewed up or something, but nothing...... Except for one of my MSD wires which was rubbing on the steering shaft. ?It was almost worn through the insulation, and I knew this wasn't a good thing, but also not the cause of this frustration.
I twisted the wire to stay out of the way. I took off the cover to the underhood fuse box, wondering if maybe a FI or Ignition fuse blew for one of the banks. ?Nothing. ?I slam the cover on in frustration. ?By now I'm drenched, and I can't find anything obviously wrong.
I start the truck up again, and rev the heck out of it. ?It was making a noise similar to a Harley trying to rev with it's choke on. "brak Brak BRAK BRAK BRA-BROOOM" ?It's spewing tons of white/grey smoke that reaks of fuel. ?I'm wondering if my block or head cracked for some reason, and I've got coolant getting in the cylinders. EDIT: ? ?Maybe some injectors are stuck open? I could also hear a distinct "Pfft Pfft Pfft Pfft Pfft" as the truck "idled". It sounded like a carbureted engine with an it's air cleaner removed...
I keep my revving up for a minute or two, trying to clean the thing out. ?It was finally able to idle on it's own, VERY ROUGHLY at about 400-500 rpm.
I go inside to talk to the g/f. ?I come out a minute later, and the trucks idling fine. ?I drove home with all 8 cylinders firing.
I get home, and pull a P0300 "Random Multiple Misfires Detected" code.
Anyone had these problems before? ?
What do you think the issue was?
