The injector is a good possibility, although you should check for spark in the wire first, as the electrical is the weakest link in the system. Put a spare plug in the end of the wire with the plug resting on metal, then have someone crank the van to see if you have spark that far, test and replace spark plug, (do not get shocked!) then look into a new injector or a good cleaning.

SOURCE: misfire #1 cylinder (autozone scanner) I changed

inspect the sparkplug plug first!! After engine is running for 20 sec (while misfiring), pull your #1 sparkplug and check for fuel. If there is no fuel replace the injector!!If there is fuel, post a comment for more help!!

Misfire on Cylinder 3 swapped plugs between 3 and 4 on Pontiak Aztek 2003. Misfire remained on cylinder 3. Swapped ignition coil 3 and 6 with ignition coil 1 and 4 misfire still on cylinder 3


Try a new plug wire on cyl 3 if that doesn't fix it you could have a bad valve or compression problem on cyl 3 Try doing a compression test also If it has injectors for each cylinder you could have a bad injector for cylinder number 3

Cylinders 1 and 3 misfiring on 2.4 Liter 97 chevy malibu


code p 0300 is random/ multiple cylinders ----misfires detected ===causes ---spark plugs ---HT lead/s---injector/s---ignition coil/s---low compression---wiring
he has changed a lot for nothing
a 5 year old engine can have a lot wrong with it --so new out of a crate is no guarantee
most misfires are from injector problems
it could be a loose valve seat insert so have a compression test done if moving the injectors to new locations doesn't move the misfire

Misfire reasons.
Bad ignition coil (there are 3 of them), bad spark plug, bad spark plug wire (most common) defective fuel injector, intake manifold vacuum leak, low cylinder pressure due to burnt valves or scored cylinder walls.

1998 chevy venture has electricity arcing across the harmonic balancer


The coil pack on these engines runs hot, so it's important to make sure there is heat sink grease under the coil to transfer heat. If the coil module gets too hot, it will fail.
If an engine is hard to start or has a misfire at higher speeds, the problem may be a weak coil, a bad plug wire, or a fouled or worn spark plug. On 1996 and newer vehicles, you should get a cylinder misfire code. A code for one cylinder would likely indicate a fouled plug, bad plug wire, or possibly a clogged or dead fuel injector, or a compression leak (burned exhaust valve). Misfire codes for two cylinders that share a coil would likely point to a bad coil.
Another way to figure out if a misfire is a bad coil is to swap two of the coils on the coil pack. If the misfire moves to the new cylinders, the problem is the coil. If the misfire remains in the same cylinders, the coil is OK and the problem is the wires, plugs, injectors or compression.
If you test a coil with an ohmmeter, the test specs are 0.5 to 0.9 ohms for the primary terminals under the coil, and secondary resistance of 5,000 to 8,000 ohms at the high-voltage terminal.

Random Misfire on 2 & 3


I had a problem with a chevy with random misffires on all cylinders. It was the computer. Fords have very few problems with there computers. Does the check engine come on? Maybe have it scanned.
