I had 4 codes that came up:
P0300 - cylinder misfire detected-random cylinders
P0172 - Fuel trim bank one condition
P0335 - crankshaft position sensor condition
P0342 - Cam sensor condition

I got the codes from Auto zone, and the print- out told me different symptoms that could be causing the code.
My fuel out of the exhaust smells rich, and sometimes my car is a bit jumpy when acclerating. Any help?

Welcome to the forum, i'd use a gage and check fuel pressure. How long since a tune-up? Pull the vacumm line off pressure regulator, check for gas.

I'd want to look at fuel trims, if it is adding fuel. I want to know, why? If your not going to use a scanner to look at freeze frame or live engine data. I'd erase the codes, see what returns.
