I have an 04 srt w/ a 50trm kit im getting codes for a small evap leak. I fixed a vac leak but i cant find anything else. It bucks at 2000 rpm, and i've been having this prob for a while. I would love some advice. thanks everyone!

 

damn...this is the third post ive seen with this type of problem. check out your throttle position sensor. you might just need to get the wires resoldered and voila. if that doesnt fix it, then i have no clue. but i went through hell and back to figure out the solution.

Does your car buck when your cruising? with your foot not moving anywhere but the car starts to buck anyways? also is your rpm gauge sticking when you rev? or does it go up and down by itself? those were the symptoms that i was having with my car.

 

another possibility would be an O2 sensor, a guy i know had a similar problem as far as the car missing, but i don't think it did any kind of bucking
