Change fuel filter? Idle?

 

Sounds like timing to me for first thought.After that i'm thinking injectors.

 

If it was gas related, woouldnt it do it even in park and at a stop.? its only under a load...dealership told me todat it might be a bad cap n rotor button... so im going to try that 1st and get back with you...everyone thats sent relpys or IMed me thanks for the help.

 

it is most likely a fuel issue... check and replace ur fuel filter first (cheapest) ... then move up and start checking injectors/pump etc
