    It was tried already. Problem persists. Now, this vehicle is never driven hard (take kids to schiool, go to the mall) and it might make it into the freeway maybe once every 2 months to have a "longer run" - 20 miles or so one way. Could it have build up?

    Thanks.

    My van just started chugging so we replaced the spark plugs, wires and coil pack. Mine is the #2. Spark plugs were swapped and still the #2 is getting fuel but no spark. What can I do to fix this?

Friend, caravans, town & countrys, and voyagers of these model year group have a known problem that should have been recalled eons ago by Chrysler. The flywheel is a 3 piece flywheel that is welded together. (It should have been a single piece, forged flywheel, if they had made it to last.) The flywheel is about 18 inches in diameter and has the cog (gear tooth ring), spot welded near the outside edge. It has a center circular piece about 5 inches in diameter that is TIG welded. As the outside turns more slowly than the inside and torque stress in transmitted to the inner circle, the stress shears the welds and caused the inner part to shift about 1/8 of a rotation, throwing your timing off. You can either 1) replace the flywheel or 2) buy a rebuilt transmission.

If it's only one cylinder... bad spark plug wire or spark plug would be suspect.... swap the plug wires from another cyclinder... at the coil pack and plug and see if the misfire has "moved"

    you could try a bottle of injector solution in the gas tank... and give it a good run on the highway.

I am having ongoing problems with the truck miss firing and rough running. Timing is ok, replaced cap and rotor,coil. It still starts rough,idles rough and misses when at cruising speed,although it seems...


Misfire is a common driveability problem that may or may not be easy to diagnose, depending on the cause. A misfiring cylinder in a four-cylinder engine is, pardon the pun, hard to miss. The loss of 25% of the engine's power output is the equivalent of a horse trying to run on three legs. The engine may shake so badly at idle that it causes vibrations that can be felt in the steering wheel and throughout the vehicle. The engine also may be hard to start and may even stall at idle, depending on the accessory load (air conditioning, headlights and electric rear defroster, for example).

When misfire occurs, performance suffers along with fuel economy, emissions and idle quality. And, when a misfiring vehicle is subjected to an emissions test, it will usually fail because of the unusually high levels of hydrocarbons (HC) in the exhaust.

What causes a cylinder to misfire? Basically, it's one of three things: 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 spark plug 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. Low fuel pressure would affect all cylinders rather than an individual cylinder, as would most air leaks. A leaky EGR valve can also have the same effect as an air leak.

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.

Intermittent misfires are the worst kind to diagnose because the misfire comes and goes depending on engine load or operating conditions. They seem to occur for no apparent reason. The engine may only misfire and run rough when cold but then smooth out as it warms up. Or, it may start and idle fine but then misfire or hesitate when it comes under load. Also, it may run fine most of the time but suddenly misfire or cut out for no apparent reason. Intermittent misfires can be a real challenge to diagnose, so let's start with a steady misfire in one cylinder before moving on to intermittent misfires.

Hope this help.
