Check the grounding surfaces on the coils. Also, check your ignition module, it may be malfunctioning.

Many coil problems are actually caused by other malfunctions.

I'd go ahead and change the plugs and wires anyway since it's always a good thing to do. I'd definitely start checking connections on the coil pack and ignition. It's most likely a problem somewhere in that range.

I hope this helps a little. Spark problems can be led from many different areas.

Replace the ignition module. they go bad all the time. do not waste your money on spark plug and wires, coil packs etc...

Troubleshooting a rough idle


Have the engine computer scanned for trouble codes. Misfires are from loss of fuel, spark, or compression. Check the fuel pressure, check that all spark plugs are getting spark, and if all good so far, test engine compression. Low compression in a cylinder will cause misfires and loss of power.

It could also be a vacuum leak- a loose or cracked vacuum hose or an intake gasket leak.

Loss of power


Get a pressure reading on the fuel pump,it sounds like a classic fuel pump going out. If it idles but cant go much faster than that then I am pretty sure is a fuel pump.

Ford 2003 escape codes readed


Cauases or fault codes are not cut and dry, but here are the possible causes of codes P0316 and P0306 which are related codes.
P0316 - Engine Misfire Detected on Startup
Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Engine fails to start
- Engine runs rough Possible causes - Crankshaft Position (CKP) sensor harness is open or shorted
- Crankshaft Position (CKP) sensor circuit poor electrical connection
- Faulty Crankshaft Position (CKP)
- Ignition System
- Fuel Injectors
- Running out of fuel
- Fuel Quality
- Faulty Engine Control Module (ECM) P0306 - Cylinder 6 Misfire Detected Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation
Possible causes - Faulty spark plug 6
- Faulty ignition coil 6
- Ignition coil 6 harness is open or shorted
- Ignition coil 6 poor electrical connection
- Clogged or faulty fuel injector 6
- Injector 6 harness is open or shorted
- Injector 6 poor electrical connection
- Improper spark plug 6
- Insufficient cylinder 6 compression
- Incorrect fuel pressure
- Intake air leak

When driving engine cuts out spits and sputters, changed plugs wires and fuel filfer made no difference


could be bad coil pack or spark plugs check coil for cracks causing it to intermitenly fire or bad plugs causing power loss.

My 1997 hyudai accent has a missfire code on cylinders 1 and 4 car has no power replaced plugs only change is the idle is much smoother. what else should i check


Main causes of misfire would be loss of spark; the air/fuel mixture is too far out of balance to ignite; or loss of compression.

Loss of spark includes anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. Causes include worn, fouled or damaged spark plugs, bad wires or even a cracked distributor cap. A weak coil or excessive rotor gas inside a distributor would affect all cylinders, not just a single cylinder.

"Lean misfire" can occur when the air/fuel mixture is too lean (not enough gasoline in the mixture) to burn. This can be caused by a dirty, clogged or inoperative fuel injector; air leaks; or low fuel pressure because of a weak pump, restricted filter or leaky pressure regulator.

Loss of compression means the cylinder loses most of its air/fuel mixture before it can be ignited. The most likely causes here are a leaky (burned) exhaust valve or a blown head gasket. If two adjacent cylinders are misfiring, it's likely the head gasket between them has failed. Also, if an engine is overheating or losing coolant, it's likely the head gasket is the culprit.

You can isolate the weak cylinder by temporarily disconnecting each of the spark plug wires, one at a time, while the engine is idling. When there's no change in the idle speed, then you have pinpointed the weak cylinder.

What causes a misfire on a 99 pontiac grand am if spark plugs or good and the car does not have wires


here are the common causes of a missfire, defective ignition coil or ignition coil wiring for that cylinder, defective fuel injector, defective powertrain control module, intake manifold vacuum leak, low cylinder compression.

2000 ford explorer 4.0 x-engine is stalling, missing and lose power while driving


I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.
