this bucking problem is driving me nuts

[Tommyg]

The car bucks only on mild acceleration--quits when 3lbs of boost or more is used. All the electronics checked out fine.Sometimes it runs fine but 80% of the time it won't accelerate without bucking--not an engine miss but feels like something is chocking the motor. Please help!!!!!

I've been having this problem too. For me, it was too rich of a PE fuel curve. I had developed an exhaust leak which caused slower spoolup which caused it to be too rich. After I took some fuel out of the curve, it helped (I still need to fix the header though).

do you have a translator? If so put the WOT fueling down to 0 or so, it thinks WOT is a lot less than what youre really at. This was causing my car to buck and act funny until it got to enough boost to use the fuel. Either way it sounds like too much fuel for the give throttle

Dont forget to check the TCC solanoid in the trans pan.If that goes your car will buck like a bull in heat.
