Disconnected MAF. Idled fine. Would not run above idle. It stalled as soon as I gave it any throttle. I let it run for about 5 minutes.
I cleaned my K&N when this started as well. I had the truck running with the filter off to dble check air flow. The truck stalled anytime my hand got near the bottom edge of the air intake tube.
Funny thing about this whole thing is my gas mileage has improved a little.
I just got back from the store. The thing runs smooth at 1200 to 1500 RPM at 65 MPH - no problem. I can't feel any bumping or surging. As soon as I try to accelerate, it surges. Full throttle, misses, surges, and begins backfiring through intake at 3800 - 4000 RPM like clockwork. A local shop says thats an indication of lean conditions.
MAF maybe not doing well, or the other sensor in the tube?
Thanks for the replies so far. This has me stumped. Please give some advice...What Next?
