It can still misfire. If you want to see if it is a misdirected spark, watch yhe engine when in the dark. the darker the better. Look over everything. Any stray arcing of the ignition system will be visible. Like that? It works and cost is nothing.If you see any arcing, We can diagnose it from ther. Good Luck, Ned-

HEVROLET BLAZER 2000 MISFIRING


Timing is off,problem with timing chain,also check fluids in ******,plus also if you have a distributer in your vehicle,if it is cracked,moisture getting in and ruining the points,-that is if your vehicle has a distributer! This will make a vehicle run rough as well.
You can have new plugs put in,but if your spark plug wires are cracked or worn,this will also creat misfire and backfiring.

The car has 28,000 on it. the motor is a 3.6, and scanner codes keep coming up as injector #6 and misfire on #6 cylinder. i have installed all new injectors, new coil on #6, and all new spark plugs. also...


Check for voltage at the plug, 12volts. Also check with a noid light when it is acting up. Wires tend to break right at the plug. check this to include pulling the wire and the plug. I've had them hanging together with just a strand or two and when it heats up it doesn't make a very good connection.

I fixed my transmission and its still missfiring, what can it be


Tranmissions don't misfire - they are just a bunch of gears.
You're engine can be misfiring - replace the spark plugs, plug wires, and cap and rotor.

DID YOU GAP SPARK PLUGS AT 0.060 FOR 3.1L ENGINE OR 0.045 FOR THE 3.4L ENGINE.DID YOU BUY AC R44LTSM SPARK PLUGS. DID YOU BUY AC DELCO SPARK PLUG WIRES.BECAUSE IF YOU BUY WRONG TYPE SPARK PLUGS AND WIRES CAR WILL MISFIRE.

Spark? cylinder head? stuck valve? cylinder wall porosity?


That cap was most likley broken upon pulling off. You need new wires.

Misfiring/popping through engine before and after tune up


If your computer malfunctions, it goes into what is called a "limp-home mode." The mixture goes full rich and fouls the plugs within minutes. You are gonna have to find a GOOD shop that can properly diagnose the computer. It can only be done on the car with proper equipment. A bad ignition module can cause this too. Advance Auto Parts, Auto Zone and NAPA will test it for free if you take the module out and bring it in.

2000 volkswagon jetta engine noise and new plugs skipping


engine is pinking,predetonation of fuel or the fuel mixture is weak which can be caused by a vacumn leak on the inlet manifold ,such as the take off for the servo ,or the manifold bolts loose.Also the timing is set wrong which could be a fault with sensor or the sensor drive ring .Without the car in front of me i cannot really diagnose a fault like this ,either get the VW mechanic to have a look and if he thinks its electronic then take it to VW
