P0304 misfire 4


There are so many things that can cause a missfire.
Just a thought. IF you switch both the plug and coil with a different cylinder it should show the missfire on that cylinder. You might want to check the compression on cylinder number 4.

You may also want to check the continuity of the conectin to the number 4 coil pack.

Check the plugs that were replaced. They may have been cheap plugs. If number four plug is fouled you may have ring problems.

Hope this helps

I have a 2002 Nissan Altima 3.5 SE About a week ago the check engine light came on, it started running rough, especially at idle. Computer diagnostic results showed missfire in cylinder 6. I replaced...


i would definately replace the coil. pretty certain that will solve your problem. do not drive with misfire or that can cause fruther damage such as catalyst failing, which is prety expensive.

I have a p0303 trouble code on my 1999 Passat. Missfire on #3 cylinder. Coil is ok, I'm lost.


coil packs very prone to failing... check compression for good readings (at least 100 - 120psi) if okay try new spark plug as these can fail under load and its the cheapest part to replace to eliminate. if misfire still present swap cylinder 3 coil with cylinder 1 coil and see if fault code moves to cylinder 1. hope this advice helps

What does the code "misfire on bank 1 mean" on a diagnostic code for a 2000 lincoln navigator mean?


Do you mean "missfire on cylinder 1", code P0301? If so, that means that the computer has detected incomplete combustion in the #1 cylinder, which would be the front passenger side cylinder. There are many potential causes to a cylinder missfire ranging from worn / bad ignition components, clogged / bad fuel injector or even internal engine damage.

However the most common cause, especially on ford vehicles is a bad ignition coil. When trying to determine the cause of a missfire on an engine such as the one in your Navigator i start with removing the plug and checking for carbon tracing, excessive plug gap or contaminants on the plug. If that checks out ok i then swap the ignition coil from the missfiring cylinder to one that isn't. For example, I would swap the ignition coil from #1 to #2 and clear the codes. Then drive around until the light comes back. If it comes back with a missfire on cylinder #2 then you know the cause is the ignition coil and it has to be replaced. If it doesn't then it is something else causing the missfire which will require a bit more diagnostics.

How many miles are on your Navigator? Have the plugs ever been replaced? If you have close to 100k it would be a good idea to replace all of the plugs. Be careful when removing the plugs, it's not difficult to pull the threads right out of the head when removing the plug.

I have a 1995 saturn sl and it just started idleing up to 3 0r 4 rpm's when i start it and sometimes cuts off going dwn the rd service engine light comes on.this morning the same thang but it now feels...


Sounds Like the Common Item on these Saturns, and that is ( (COIL PACK) you Probably have the Missfire on Matching Cylinder BANK . You DO NEED to Check For Codes to ZERO in on it I think you will see a CODE po161 - 166 < I Believe these are the Codes that set for MISSFIRE .
