Well this is kind of puzzling? I have been having a shifting issue when I come to a stop and proceed to go I get a shudder and when under a load like pulling a long hill it seem like I really need to get on the gas to get it to go ( sliped this after noon ) Car has a whine I have ruled out pulley issues. Had the codes scanned and it came with a temp sensor and the dreaded O2 sensor code that I think may actually be an O2 sensor. I checked for vacuum leaks none I checked for a bad fuel regulator and it's dry. Also it won't idle correctly it's up around 1000 rpm and it will drop to about 400rpm studder like its going to stall but it revs it self up? Fuel mileage mixed is around 17 mpg mixed driving I was getting better from my suburban! Any help guys! I really like the car I don't want to be in the market for another car!
