Misfires and Their Causes
Ignition Misfire
An ignition system problem is one of the most common reasons for an engine to misfire. As the spark plugs, ignition cables, distributor cap and rotor, and ignition coil wear over time, their ability to transfer the needed spark to ignite the air/fuel mixture inside the combustion chambers becomes compromised. In the early stages, the spark will only be weaker and the actual misfire will be subtle. As the ignition components continue to wear, the misfire will intensify and the combustion process can be interrupted completely. This will cause a severe jerk or shock in the operation of the engine (the engine may even backfire through the air intake system, producing a loud "pop").
Lean MisfireThe lean misfire is another common reason for an engine "miss"-this is due to an imbalanced air/fuel ratio (too much air/too little fuel). Since an engine needs a richer (more fuel) mixture for a smooth idle, this problem may be more noticeable when the vehicle is idling. The lean misfire may decrease or disappear as the engine speed increases because the efficiency of the volumetric flow into the combustion chambers increases dramatically. This is one reason why a vehicle gets better mileage on the freeway than in the city. An EGR valve that is stuck open, a leaking Intake Manifold Gasket, a defective Mass Air Flow Sensor, a weak or failing fuel pump, or a plugged fuel filter are some of the many causes for a lean misfire.
Mechanical Misfire
Mechanical problems can also cause an engine to misfire. Common causes of a mechanical misfire are worn piston rings, valves, cylinder walls, or lobes on a camshaft; a leaking head gasket or intake manifold gasket; damaged or broken rocker arms; defective fuel injectors (and/or the electronics that control them); and a slipped or incorrectly-installed timing belt or timing chain. Generally, this type of misfire has more of a "thumping" feel to it. It is usually noticeable regardless of engine speed; in fact, it may even intensify as the engine speed increases.
Powertrain Misfire
Sometimes, the engine has nothing to do with a misfire. One common cause for "jerky" performance that feels like a misfire is a problem in the transmission and its ability to properly up- or down-shift. If the misfire occurs during higher speeds, it could be a problem with the operation of the overdrive gear or a chattering clutch in the Lockup Torque Converter. If the vehicle jerks or feels like it is "missing" during deceleration, it could be due to harsh transmission downshifts, badly warped rotors, out of round brake drums, and/or sticking brake pads or brake shoes.
Make sure that you have the vehicle properly inspected in order to determine the root cause of the misfire. Entire engines have been replaced to solve a wrongly perceived mechanical misfire problem that was actually rooted in the transfer case, transmission, driveshaft, or front/rear differential.

2004 chrysler van 3.8 motor replaced coil pack still doesnt fire number 4 cylinder


If the coil pack has a four wire connector, one wire is primary voltage, the other three wires are ground, one ground for each coil, one coil fires two spark plugs. If problem with coil or ground, you would lose spark for two spark plugs. Did you visually check for spark, everywhere? What about the spark plug wire or the spark plug, itself?

Why would an 2005 Town and country van with a 3.8 engine start and sound/run good for a couple of seconds and then starts missing real bad.


Crankshaft position sensor maybe , throttle position sensor , coolant temp. sensor etc.... It could be a lot of thing's . Instead of buying this part an that part ,take it an have it diagnosed . To a good ASE certified repair shop . Unless you like buying unneeded parts .

My service engine light is flashing.the van is also running rough.1996 town and country van over 200,000 miles but maintained well


On yours, it's a misfire. Plug, wire or coil pack. Have the codes read. this will tell you where to look. 301 is 1 cylinder 303 is # 3. and so on. Pull the wire off the coil, have it close, no spark, replace the coil. Spark, do a tune up. Plugs and wires.

Have a 2002 chrysler town and country, stumbles and back fires, have a code p0302


#2 cylinder misfire. Plug, wire, or coil pack. One of them is bad. My guess is the coil pack. Pull the wire off the coil, lay it on top the coil close to the #2 port. Start the van. You should see the coil throwing an arc to the plug wire. No arc replace the coil. If you have arc, then replace the plug and wire. I would do all of them.

Would a 2001 chryler town and country faulty engine module cause number 2 cylinder not to fire


not likely, since the engine module also fire the plug across from the #2 cylinder on the coil pack. check for spark directly at the coil, if none is found ,then most likely a bad coil pack.

Ignition coil not sending fire to number 1 and number 4 on 2005 town and country


Sounds like it shorted out. Never worked on a mini-van. I try to avoid them. Does the coil pack plug into a tray, like on a late 90's cadillac? If so that tray needs to be cleaned or replaced. Make sure the terminals in that tray are not shorted across, meaning the power hole isn't touching the ground hole, with anything conductive.
