SO! I crank my car, and its **** bricks or something very choppy idle and it almost dies after I give it a rev, ive tried resetting my PCM and it still does it, but the weird thing is this problem only happens every so often, and I have noticed a lose of power around the 2k rpm range. any suggestions?

ps. ive checked all the plugs, wires, injectors. Im outta things to check lol

Unplug the MAF and see if it helps.

What would unplugging the MAF do?

it would force it into speed density mode and if it stops giving you problems... it could be your maf going out.

agreed. I've heard of this happening before and doing the same thing.

What exactly does speed density mode do? Sorry for the questions lol ohh and I tried it and it still bogged down and acts like it wants to quit, but when I plugged it up it fixed, the maf is basically brand new.

Speed density just reads off the programmed Ve tables. Doesn't use the maf to correct for air differences. IMO it wakes a car up a lot if you do just a speed density tune. I'm doing that this summer.
