The system is dependent on the impulses from the crank and cam sensors for ignition to work properly, and the fuel system depends on tach pulses from the ignition in order to dispense fuel. If you lose spark, you lose fuel too. Check the sensors.

If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

    Another possibility is a problem in the fuel tank. The electric fuel pump connects to the fuel line by way of a short flexible line to the steel fuel line that comes through the top. That line is known to rupture, allowing fuel to spray back into the tank and preventing the system from developing the correct pressure to run properly. A test of the fuel pressure will reveal if this is your problem. You will probably have to drop the tank to repair it.

You put something back the wrong way.....any amount of water in the tank, carb or whatever WILL NOT cause the engine not to fire.....check any wiring/rewiring you did for accuracy

check the connection of all of the spark plug wires to the plugs, you may have put a wrong one on, when cleaning the gas tank as well it can dislodge a lot of dirt, cleaning injectors and a new fuel filter could solve the issue as well

Hi, my 1996 pontiac 3.1 just got the service engine light went on along with rough idle. Took it to a auto store they hooked it up and said that cyl 4 miss fired. Any ideas. Tune 6 months ago full tank...


either injector, or plug wire or plug-I'd vote for for the plug wires first, and you can check the injector by using a broom handle and holding it against the suspect injector-see if it clicks while the engine runs. Compare it to others to see if it sounds the same. You might also remove the plug and see if it is wet (bad plug wire) or dry (injector, possibly).

1999 gran marq has new alternater,fuel pump and filter,spark plugs and boots but still skips while idleing and mostly while accelerating,,,getting worse also


I will try to add a few things to check. It sounds like bad plug wires or a coil going out. Sometimes if you water mist the coil and wires with a spray bottle you can see the sparks jump. It will be easier to see in a dark area with the motor running.

The Intake manifolds were changed from metal to plastic to prevent carbon buildup in the EGR passage. This would be under the Metal Airhorn and under the gasket where it attaches to the top of the Intake. There is a groove to clean that carbons up and throws bad codes and interferes with the engine running good. 8 bolts and a $10 gasket and 1Hour of your time to fix it.

You have not mentioned any codes or testing results. Your onboard computer can be checked for free at Autozone or Oreillys. Your "check engine" light should start setting defect codes if your misfires are getting worse. Also, if you can remember a wet plug when you removed your old plugs, that would be a good indicator of a bad wire for that cylinder.

Let me know if you have been fixed.

All of the suden started running rough, changed fuel filter, cap rotor and plugs & wires 6 months old, could it be as simple as bad gas or water in it, if so what do you do add good gas?


could be a coil or even a ignition module issue. I doubt its a gas issue. Could be clogged injectors or even a failed injector. You need to determine what cylinder is misfiring by unplugging wires untill you find the one that doest change the RPM. Also a intake gasket leak could cause a given cylinder to misfire.

Car jerks while taking off; changed fuel filter


get a scan tool to retrieve the dtc (diagnostic trouble code).
you will get a misfire code.
p0301 for cyl 1
p0302 for cyl 2 and so on.
i can't recall if that engine has plug wires or coil on plug but if its coil on plug replace the coil corresponding to the cylinder misfire

If the car has over 100,000 miles on it, you may need to replace the distributer. I don't think the bad gas caused this issue I think it may just be a coincdence. But if you already changed the plugs, wires, distributor cap, and rotor, I would definetly check the distributor.
