SOURCE: Service engine soon light is flashing

When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.

Ex. P0401 means there is misfire on cylinder number 1

P0400 is a random misfire detected.

If you take it to an Advance or Autozone they will usually scan if for free.

By the way, if you used cheap plugs instead of platinum plugs that could do it too.

Hope this helps.

SOURCE: 1999 Chev Suburban 110K miles well mantained. It

My 99 Suburban does this when I pull a horse trailer and drive over 55MPH. It will go out when I unhook the trailer and drive it around a bit. A friend told me the same light has been on in his Chevy pickup (about the same year) more than off. He has ignored it for years and no problems. Another friend who is a mechanic, (albeit a Ford guy) says the joke around his shop is that it's really the "engine ready light"! If you've had everything checked out and all you get is the misfire reading (same as mine) then get a sticker to place over the offensive light and enjoy everything else about the great vehicle you have- that's what I do!

2006 Mazda 6 3.0L. Got a misfire Cyl. #6. Replaced spark plug & coil. Still misfire. Swapped coil and same result. #6 misfire?


Could be the ignition control module (if it has a separate one, most are part of the computer now). Is it throwing any other codes, like cam or crank sensor?

Emission control check engine light


The codes indicate a cylinder misfire on cylinders 3 and 6. Seems to be a common problem with that model. I would call the dealer and ask if there are any recalls or technical service bulletins on your particular car. Could be fouled spark plugs or bad valves or bad valve adjustment. There may also be a software fix but since the car is noticeably running rough I would suspect a hardware problem. Good luck.

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.

Number five plug not firing


I'm assuming this is a DIS(distibutorless ignition system).If it is,the most common cause is a defective coil pack.Each coil will fire a pair of cylinders together on 4 and 6 cylinder engines(one "waste" spark,one to ignite the mixture).Try swapping the wires at the coil pack to see if the misfire follows the coil tower,or the same cylinder misfires(keep in mind that a check engine light means you will have to clear the code to get the computer to feed that cylinder fuel before you start it up again).If the other cyl on the pack now misfires(i believe 1+5 are on the same pack on a Ford engine),then the coil is bad(spark is "leaking"to ground).If the same cyl still misfires,try swapping a wire+plug from another cylinder.

Codes say Cylinder 4, 5 & 6 are not firing. This could be a spark issue or a fuel issue or a mechanical engine failure. Is compression zero? Did they use a compression tester?

Check engine light is on code is P0306 which I believe is the 6 cyl is misfiring. How can I test to see if it is the plug or spark plug wire


Spark plugs don't fail to fire
Wires last,sometimes,the life of the veh,20 years

Go with bad coil pack or COP Coil #6,which ever applies.

Engine warning light comes on, diagnostic says


if your car give you i code thats says mutlipul misfire on number 1,2,3,or four cyl. that means that that cyl is not firing when its suppost to so if the code says number 3 cyl misfire or multipul misfire replace number 3 spark plug and coil pack and 80% of the time that will solve the problem.
