So I got 3 codes here...

P0336 Crankshaft Position Sensor A Circuit Range/Performance (I have a new sensor ready to install)

P0301 Cylinder 1 Misfire Detected (Thinking its due to the Crank sensor)

P0122 Throttle Position Sensor/Switch A Circuit Low Input (Bad throttle position sensor?)

Your input if you got any lol, Not serious issue right? just sensors that have gone bad within the 173,000 mile life? lol
