I have a minor hesitating when I go to pull away... if I try and pull away hard it will cut down and then pick up and pull away hard... but if I stage it up a little bit, even to around 1100 rpm it isnt there...even in park and i hit the gas, it will bog down and then pick right back up again..

IAC - 29-30
MAF - 5-8
Feul Pressure - 43 psi
BLM is at 153

I have TA-49, MSD #38, Reds 93 chip

Any ideas?

That BLM is pegged! Never should be so high. Might have a big air leak in the header system prior to the O2 sensor. Plugs may be carbon fouled. Check the coil pack and wires for problems, too.

i figured that was really high.. checked for exhaust leaks, none..

i have a brand new set of taylor 10.4mm wires on it and the coil pack seems perfect.. what else would make that high BLM??? I looked for vacuum leak, but can't find any vacuum leaks either....

what else could it be? at WOT it locks on 128 ... that is normal right?
