I scanned my suburban an it says misfire cylynder 7. i jus had new heads an all put on a month ago. had a valve barely tapping..... over a week got a lil louder... this morning i was driving an the light...


Call him up, it sounds like that head is going to have to come off again. You definitely have a serious problem at # 7. Maybe a valve keeper that wasn't all the way in or possibly a bad lifter. Either way, don't drive it until it's fixed, it'll just make it worse.

Runs rough at start up,then runs okay, Hesitiates momentarily when moving from a stopped position. Occasionally wont start and runs rough, then runs okay. This problem is intermittent


you have a bad injector, if you have A... as it states on the top of the motor 2.8, 3.1 L MULTI PORT and dies or idles really rough and the exhaust smells like strong gas. most likely you have an injector that has shorted or is shorting out and from my experiences usually after a road trip or using fuel injector cleaner or buying a used car. it will cause half the motor to not run or run poorly VERY POORLY or even burn out 1 injector fuse out of 2 under hard acceleration or idles but as soon as you touch the gas pedal dies. but only if it is a MULTI PORT fuel injected motor. ive heard you want to try and replace them with bosch injectors out of a 2.9l ford bronco/ranger. only attempt if you got the mechanical know how sometimes if not done right will leak gas because of the injectors being kinda different length. research before attempting.

1993 nissian p/u run rich and it running real rough


If it is a carb engine have the air fuel mixture corrected by adjusting the screws on the carb. Try also adjusting the idling.

For EFI engines see if you can check the Idle Control Solenoid Valve, have it cleaned. You can also check the oxygen sensor if it is working or not

Air filter light on, has new air filter


The issue is not the purge valve. If you have a strong odor of gas, and no fuel leaking under the car, you have one of the evaporative emission hoses compromised. Can you get the car raised on a vehicle hoist? If so, check the lines that run along the side of the car, I will bet that you will find pin-holes in one of the evap lines. Get back to me if you need more info.
