Bought this truck a month ago and it's had quite the misfire since i bought it. Checked the plugs which looked great. Pulled the codes (someone pulled the check engine lightbulb so i thought it was throwing no codes) Came up with multiple knock sensor, multiple 02 sensor codes, and 2 camshaft/crankshaft correlation codes. Ive also noticed my tach is very jumpy, it doesn't make smooth transmissions as the RPMS climb or fall. Crank sensor? Cam position sensor? both?
