(I think I initially posted this in the B5 forum accidentally; my car is a B6, not a B5...)
I have a 2007 Passat with >120k miles on it. For the last month or so, occasionally when I start the car up, the EPC (I think it stands for Electronic Power Control) light and the Check Engine (the engine sign) light comes on. When I hit the gas, it barely goes past 20 and seems to be revving really high (almost redlining) before it finally accelerates. Needless to say, this is not a good thing; especially when it happens on the freeway.
I called around to a few mechanics but they all want to see the car and run the computer codes on it before they even tell me what's wrong with it; which I am loathe to do just yet because I don't want them to charge me an extra $100 for a diagnostic for a repair I may not even get done with that mechanic. Meanwhile I'm driving around feeling like I should put my feet on the ground like Fred Flintstone to gain speed.
In the research I've done online, I've seen that it may be an issue with the throttle wire or some other wiring issue. My question is, has anyone else had this problem, and if so, do you have any suggestions? I'd like to at least get an idea of what the source of the problem is and how much such a repair would cost before I go somewhere and get sticker shock. (if there's another discussion thread somewhere on this forum regarding this issue that I may have overlooked, that would be great too; at least I'd know that I'm not alone, haha)
Thanks in advance for any feedback you may be able to provide!
