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!!

After changing the coil pack and spark plug, why is it still skipping?


Timing could have jumped. Could be a bad head gasket also. even possible to be a small hole in piston check the cylinder for compression. Check the fuel injector to that cylinder if you have bad air to gas mixture it will throw a code of misfire change fuel filter check fuel injector to see if clogged. most likely it is the fuel injector .

Replace spark plugs and look at coils. Sounds like a misfire at idle. Car is trying to keep idle high enough with 1 or 2 cylinders misfiring. Car compensates then revs up as the cylinders catch and run again. These cars often have bad coils. Scan car and look for codes 301 through 306. Replace all plugs and if misfire comes back then replace the coils on the cylinders that occasionally misfire. Look at boots and spring wires on coils and replace coils that have bad boots.

What causes engine misfires to stay after new plugs and coil packs?


Try swapping the coil packs around - like swap #1 with #2, and swap #6 with #5, see if the misfires MOVE with the coil packs swapped to the new cylinders or if they stay with the cylinders. If they move with the coil packs, the new coil packs are bad. If they stay with the cylinders, there's a problem with those cylinders. You DID replace that camshaft sensor, right?

Have you checked your #1 and #6 injectors?

2002 ford escape misfiring changed all plugs gaskets boots


I would have it scanned and check what cylinders are still misfiring. I would change the ignition coil for that cylinder and see if that fixes the
problem. If the misfire is still there...the PCM will likely need replacement.

I have a misfire in 1 cylinder I had just bought spark plugs and wires I went back and reguaged them all and it still has a misfire what else could it be I have a 2001 Mercury sable.


It could be a coil pack. Follow the wire from the spark plug back to the coil pack. each one should run two cylinders. Switch the coil pack with a different one and see if a different cylinder misfires. They are easy to change, just 2 7mm screws hold each one on.

not only did the problem switch cylinders, it switched banks. cylinders 5&6 are on the drivers side and 4 is on the passenger side. i would recheck all wires to make sure you have the correctly installed.

Engine misfire


It sounds like the coil is going out on that cylinder,but replace the boot with the coil.It would not hurt to use a injector cleaner first,Lucas is the best.

Detected a cylinder 2 misfire on 02 audi a6


Chances are you have a faulty spark plug on cyl. no. 2. If new plugs are in the budget this would be a good starting point. Use a quality plug from your local "auto house" e.g. NGK. For futher pinpointing you can move the suspect plug to a new cylinder location and see if the code comes up for that cylinder.

#5 cylinder misfire


I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.
