so i ran the diagnostics today on my car and i got code 11, 12, 13, 33, and 42. The crank position sensor, my MAF sensor, my fuel temp. sensor, my O2 sensor, and my head temp. I've been lookin around and can't find anything on the fuel temp. sensor or the crankshaft position sensor. Any suggestions where i can get these besides a dealer. I guess all these problems would solve my hesititation and chugging problem wouldnt it?
