I had some repairs done, at a GM dealer, for a coolant leak (outside the engine) and fuel pressure leak. The Fuel Pressure leak has been around for awhile, and I decided to get it done while the car was there. Ever since then it's driving much slower and the RPM gauge doesn't exceed 4000, which is hard to get it up there. There are no codes (SES not lit). I haven't taken it back yet but I mentiioned it to them and I didn't like the baffled look on the mechanics face. I've noticed when I push the pedal that there is a lot more resistance then before. Whether the car is in limp mode or not, it would be nice if anyone here has any clue what could be causing this before I take it back.
Thanks!
