A compression check should be done to make sure that it is not a compression issue, also you can plug in a node light in place of the injector to see if the ECU is firing it off, then check for spark at the plug,

there is very little you can do by pulling out the ECU, most of the diagnostic work on the ECU is done through the OBDII port using a scanner,



hope this helps

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

2001 buick century P0304 step on gas engine light starts flashing


P0304 is engine misfire #4 cylinder Several things can cause a misfire #1 electrical which you have covered #2 Mechanical Test engine compression is should be around 150 cranking and 120 running . internal valve train components can cause bad compression and the valves then self. #3 fuel injector can be the cause suggest swapping with a know good cylinder and see if misfire follows injector.

Kinda putters then engine light came on and its giving me a code p0303


p0303 is a mutible engine misfire on number 3 cylinder. the best fix,

A code P0303 may mean that one or more of the following has happened:

  • Faulty spark plug or wire
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Running out of fuel
  • Poor compression
  • but first of all check the wires and sparkplugs first!

I have a ford explorer 99 but it's giving a error code PO306 what do u think it is


It sounds like a misfire. Check spark plugs 5 and 6. It could be bad fuel, bad plug wire, or weak coil. Check the fuel injectors as well. Other possible causes could be an egr valve stuck open, vacuum leaks, low fuel pressure.

Misfire #3 cylinder


Has anyone found the problem? My 2003 has #3 cyclinder misfire and I have replaced the plugs and wires. It runs rough at idle but smooths out at highway speed. Anyone have any knowledge on this? This sounds like a common problem.

Ford mustang - year 2000 - 3.8 liter. The coil pack is out?


I replaced the coil pack to no avail. I also purchase a code reader while at the auto parts store. This device told me cylinder 3 was misfiring (P0303). I found that the spark plug wire had shorted out on the manifold sensor tubes. Replaced that wire and done.

I highly recommend keeping a code reader in your car tool kit. very useful.

Engine misfires


You didnt mention having changed the spark plug wires, so that is another item that could be culprit as well. As well, it could be a coil pack that is not working properly.

I cannot recall at the moment if that model year uses coil on plugs or if it uses coil packs. Either way, if it uses a coil on plug set up, take the one for the #3 cylinder and move it to say #4 or anyone of your choice and see if the misfire follows

If it uses coil packs, there is likely one coil pack that controls two cylinders. In that case just swap the coil pack with an adjacent one and see if the problem follows. Pay attention to where the spark plug wires go because it will be an issue if you get them mixed up. You just swap the coil packs around.

I would, however, start with the spark plug wires if you have not changed them already.

2000 VW Jetta VR6 My check engine light started flashing. My car was idleing very rough and missing. The parts store checked and the code showed misfire 1. We replaced the spark plugs. It runs a little...


You may have a bad coil pack - try moving two of them around and see if the misfire follows the coil pack or stays at the same cylinder. If it follows the coil pack, get a new one. If it stays in the same cylinder, inspect your spark plug wires and make sure the plug is gapped correctly.
