Sounds like he has it sorted. Get it thoroughly checked over for bad leads, poor compression on one or more cylinders, valve or valve gear damaged. Its 15 years old, has it been regularly serviced? What mileage has it done? Is there oil in the water or water in the oil leading to the head gasket leaking. Something which happens after running without proper coolant which rots the gasket.

Your flywheel sound like it has hot spots on it, making the clutch chatter. You might need to pull the flywheel off and get it re-surface. This is like turning your rotor, or brake drum. If you pull the flywheel, you will see discolor spots on your flywheel. This is called hot spots, and will make the clutch slip.

On the other problem, have you changed to fuel filter and fuel pump. It almost sound like your running out of fuel????

I'd check the motor mounts. Shuddering upon acceleration indicates movement of the engine inside the compartment. Best of luck.

check your wire harness on the top of the engine. Volvo must have bought harnesses from Mercedes. The insulation just cracks and disintegrates, then the wires short. Not good for an ignition system.Once they short It can fry the circuit for that cylinder in the computer. Does not set a code other than Misfire.

SOURCE: My 2002 Ford Ranger Edge V-6 is misfiring.

havent a clue here ,one cylinder now another missing ,only one thing comes to mind here and thats the coil pack ,check the voltage across the battery with engine running at 1500rpm and if its higher than 15.5 volts of their abouts then the alternator regulator is playing up and this would cause problems with the coil pack or the ECU ,also the radio could blow and lots of bulbs.Other that this i would need to get my greasy hands on it and give the magic hammer treatment

2010 Jeep Wrangler unlimited sport extreme shudder at 40 mph- if I press the gas-pedal and get the RPMs to rev, the shudder ceases, only to return once I am back down around 38 mph-41mph.


which engine the 3.6? v6?
that shudder is called MISFIRE.
get a tune up yet, even $1.49 spark plugs?
no its not the trans,
if it dont slip, its not trans, (see RPM races? that is slip or too low gear)
if it shifting to the right gears, its not the trans can you count them?
is the CEL lamp glowing or flashing driving, is yes, that means
scan me now. in fact scanning while it shudders, is like (magic)
why start guessing, do a tuneup,
then scan it.
if its is misfire the PCM will tell you what cylinder misfires.

are your spark plugs 6 years old, if yes, why?
going for 200k miles on them.?

You may have a trouble code without the check engine light, but normally the light comes on too.
The code was probably 304 which means cylinder 4 is not producing power. That can be caused by no spark, no fuel, or no compression.

My 2002 ford escape says cylinder 2 and 4 are misfiring. The check engine light keeps coming on and it shakes and shudders at low rpm.


Hello, You may have already had the motor scanned if you know which cylinders are misfiring. If you need a scan, go to Autozone, Advance, or Oreilys for a FREE scan to diagnose your problem.

The shaking and shudder are normal when you are losing half to a third of your cylinders. If you are confident of the cylinders that are to blame, you need to investigate why they are misfiring. The sparkplugs can be bad by now, but were probably good before the spark to them was interrupted.

Your vehicle has a coil on plug system. There are reports of problems on the NHTSA site but no Recalls were issued. You need to change the 2 coils and plugs for those cylinders. The problem will make other components like your PCM fail if it has not already been damaged.

The electrical system in the PCM gets damaged if the spark does not flow to the sparkplugs. The built up power can charge the chassis and knock out delicate small electronics so do not delay in fixing this.

Also the reports I have seen do not show any advantage to replacing all of your coils instead of the damaged 2. If the shuddering continues after the coil/plug change, you probably need the PCM. I know this is not good news but hope my solution is very helpful.

Vehicle shudders and sometimes dies. It shudders


Check the EGR Valve for stuck open condition with a vacuum pump.

If at idle you apply vacuum and it gets worse and shuts down or shutters, then that's not the problem. But, if you apply vacuum and there is a leak, there is a bad EGR valve on the car. If you apply vacuum and it operates the EGR and there is no change then the EGR should still be removed and the pintle cleaned, or a new EGR Valve should be installed.

Also, a coil pack could be causing this condition, where not enough spark gets to the spark plugs.

Is this a 4 tech or quad 4 engine?

Also, the cylinder head gasket could be burned through and allowing one cylinder to bleed exhaust to another cylinder on the Quad 4.

Good luck with this.

1998 ford expedition misses, ,shudders, replace spark plugs 6 months ago, and 2 COP's. #4 misfires again!!


The coil is not seated correct or it has become bad also. These have a tendency to mess up on a regular basis. I use a di-electric grease on mine to help it from misfiring. I would take that #4 back off and re-seat it and see how it performs.
