UPDATE: I have replaced the MAP sensor hoping that was the problem. However I drove it tonight about 30 miles and the CEL came on again. I havent had a chance to check the OBDII code yet but I suspect it will be a P0171 Lean Air/Fuel ratio again.
I think I may have to go over the vaccum lines and the intake again looking for leaks. I havent checked the exhaust system for leaks yet and I think it may give the 02 sensors a lean reading if there is a leak there, correct? Any input you have would be greatly appreciated. Thank You
