Attempted to burnout at a stop sign while it was raining on black top and it started jumping violently until I let out of the gas and it cleared up. pulled some codes for o2 sensors and egr valve so I cleaned the egr and its still the same. it has 164,xxx miles. whats the problem??

From your vague description of "jumping" not sure what you mean...engine or entire truck?

I would guess wheel hop because it ended when you let off the gas.If that is the case the codes pulled would be irrelevant.

to answer your question...the driver.

If you want the other problem, the dtc, diagnosed why don't you post the codes.

ok its like turning a light switch on and off, the truck cuts out then picks up, cuts out, then picks up, so on and so forth..

and its the entire truck that jumps. it wont do it while up to speed. only when I try to take off hard

nobody?

Like stated your description is iffy.....post the codes and give more details.

That's why your not getting any responses...we can't read your mind.

Just trying to help.........shot in the dark....sticking butterfly in the Throttle body
