My old post said it goes to 2000rpm's and then dies, but that's not exactly correct. It seems to start everyday after sitting overnight or until it cools off and runs well for 2-3 minutes before starting to misfire, hesitate and generally run like crap. I've gone over every vacuum hose, checked the air cleaner intake from MAF, fuel pressure etc. Still the same thing, after a week. I replaced the PCV valve, took out the brand new plugs(black from misfires), checked all electrical connections. Fuel filter's next, but I doubt it. I get no codes, no check engine light, nothing. My exhaust system leaks at the O2 sensors, but that I can't believe that would be it.
I'm thinking now it's gotta be either the MAF(remember no codes tho'), the Ignition Module or Emissions/EGR, since the truck runs fine until it warms up. Kinda feels like once it starts emitting warm exhaust, the problem begins? I don't know.... How does one check the EGR and the Ignition Module?
Does anyone have any other suggestions. I'm running out of options and patience, as she was running like a top beforehand, and I miss her!
Thanks guys.
