2003 ZX5 2.0 DOHC - Rough running
I hope someone can point me in the right direction.
Thanks in advance
Was driving and heard a faint rattle or bang from underneath the car and suddenly the car felt under powered, sputtering like it was thirsty for gas. Check engine light did not come on. I replaced the spark plugs, coil pack & fuel filter, and then CEL came on. Got codes p0460, p0316, p0304, p0300, p0301
The engine seems ok in park until its in gear or reverse. Its cut off while driving to get the codes, even after adding gas but I only put in 2 gallons in case the gas tank needs to be dropped. Oil and transmission fluids look good. The exhaust coming out is choppy. It had a strong sulfur smell until I added Cheron Fuel System Cleaner and more fresh gas. I hear a noise from the fuel area when starting the car, so I think the fuel pump maybe good. Fuel gauge has been out for awhile with no noticable problems until this happened. Car has 94k miles
