When driving the car in the city at speeds below 35 miles per hour, it performs well, but when I take it up on the highway, or attempt to take it up a steep hill...it looses power. The tac still climbs when I step on the gas and the engine rev's up, but the power just isn't there. I pull to the side of the road and let the car sit for a minute or two and it's as if something resets. It doesn't work the first time every time, but it's the only thing that gets the car moving again. It's a nice looking car, but after spending hundreds of dollars at a GM dealership, I still have the same problem...I also loose my blinkers every now and then...I don't mind spending a few more dollars, but not on guesses...I want the problem fixed.

Started up fine, died at the gas pump (live across the street from the gast station). Wouldn't start. NExt day started, rough idle, engine misfire. Found broken vaccuum line and bad map sensor. fixed it up, still have same problem. Tested ICM, coil pack, and coil housing, all tested fine but found 2 small crackis in the housing. Replacing it later today. Originally got the infamous po300 code...agh!
