My car loses power (when i am on the gas pedal, it starts pulsing/jerking around), and sometimes, not all the time (i believe it would everytime if i kept driving), the epc light comes on, then it loses most of its power (some sort of system that saves the car ultimately). If i turn the car off and sit for a while, it goes away (again depending on how long a drive it for).This happened to be a couple of months ago, and i brought it to Garvey(VW dealer). It tripped a couple of codes...they didn't know what was wrong,so they reset them. Ended up bringing it back next day, they called aorund and no one knew. They cleaned the grounds and that worked...up until a couple weeks ago, it started off slow and began happening everytime i drove the car. I brought it back, it tripped the same codes, plus 2 more! This time it tripped a throttle body code. They still didn't know what to do (didn't feel safe using my money to guess on what to fix...even tho i got slammed twice already to find out that they didn't know what to do). We picked the car up, and they told us, after sitting in the parking lot all day, it runs crapy and the EPC light is on right from the start. PLUS, now my check engine light is on (it was NOT on when it went there) Does anyone have any suggestions? We were thinking about puting a whole new throttle body system in the car, but it is $600, so if there is a cheaper solution, i would love that =] Thank You!
