Error code P1391 for my 97 dodge dakota, slt 4x4. when i reach 50mph, and i release the pedal and press the pedal, my truck shimmy's, just for a second, my truck starts every time, just takes about 2-3 seconds, and i do smell quite a bit of gas. I think it is the crankshaft position sensor, how can i know for sure, do i need a voltometer to test. I also got a code for o2 sensor, high voltage bank 1, sensor 1. can anybody help me?
