check out this tool. Brand new on the market and it quickly can diagnose a misfire from the plug or the coil pack. Here's their website

SOURCE: 2000 cadilac deville dts started with a missfire

is there a check engine light on? did you change the spark plug wires?
you may have a intake gasket leak or possibly a cracked intake manifold. there is a simple test to try to determine if there is a leak in the intake but it can be potentially hazzardous. with a can of carberator cleaner, spray around the intake gasket and manifold. if the engine revs up, there is a leak. you can also purchase a vacuum gauge and test the amount of vavuum the engine makes. typically 17-22 hg. connect the gauge to a main vacuum port such as the hose to the brake vacuum booster

SOURCE: how do i fix my 2001 cadillac catera idle problem

The problems you are describing indicate to me that you likely need to replace the coil pack that runs from the spark plugs ,and the plug wires end up at it.It also may be the spark plug wires,get a water bottle and spray the wires after dark and if you get a light show from them then replace them,if not,replace the coil pack.

Possibly a bad plug. Check the compression on cylinder 5.

2004 Sorento began with code P0305, cyl #5 misfire. Inspected and replaced plugs, wires, and coil pack on cyl #2. Repair shop told me cyl #5 injector bad so they replaced. Still has misfire.I suggeste


If you had code P0305, I don't know why they would have done anything to the #2 cylinder but if they have already replaced the plugs, wires and injector; here are a few more items to check:
1) Check connections from ECM. Look for any corrosions or bent/broken pins.
2) Check the fuel line pressure
3) Check the engine compression
4) And if the above are good, then you will probably have a defective ECM

I would say its the coil. A crank or cam sensor could cause one cylinder to miss, or go completely dead, but I doubt it would affect two cylinders. And you would get a code for either sensor.

Po300 code multi cyl misfire any sugg


The code you got may not have indicated the correct coil, that was bad

I would put the old coil back in #6 & either walk the new coil to another cylinder, or get professonal help in the form of a scan tool in Mode $06,
if applicable on your vehicle & check for misfires that why

Forget the PO300

Sport Wrangler 6 cyl. Engine lite flashing. Diagnostic tool lists code PO305. I looked it up and it states misfire in cyl #3 & 5. How do I fix this?


Check the plugs, wires and coil pack for these two cylinders. Most lilkely it is the coil pack, they work for 2 cyclinders at a time. cylinder motors use 3 and 8 cyl moters use 4 of these. If your und=sure where the coil pack is, follow it backwards from the spark plugs.

I was having the same problem changed plugs, plug wires, coil packs, cat converter and had injectors flushed....cost quite a bit and nothing fixed the problem. Over 1000.00 spent before changing the injectors and this fixed the problem perfect.

2006 dodge caravan, 6 cyl. relaced cole, sparkepugs and wires in oct. 2009. Engine is reading #2 cyl. misfire again. Why


Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !

Use the correct champion plugs for starters, make sure the wire is firing. If the wire is firing, the coil pack is good. You will need to check compression and fuel delivery after that.
