Have any body ever encounter this problem. My Gsr hesitate from 0 to 2500 then picks up. I'm thinking it just needs a wire,cap and rotor. And even a fuel filter.

 

Same **** happens to me. Car kinda bogs and the pedal builds pressure and jerks, den moves back forward.

I have tried everything, well mostly. Check for a vacume leak (even a tiny one)

Make sure no water are in your cylinders. Uhm, clean your injectors..

Oh, do you have low idle at times?

 

I don't know whats going on, but it doesn't do it all the time. But it doesn't low idol. And even when i open throttle it it does the same thing.

 

thats how my car is i can like floor it at like 1500 and it will slowly get like to 3 grand and then finally get power....you could try checking ur timeing
