So the Crank Position Sensor didn't do the trick, darn. I'm just about ready to just go ahead and change the O2 Sensor. I'm told it shouldn't be the problem since the misfire is happening during a cold as well as a warmed up engine and the O2 sensor should only cause the misfiring at warmer...

I finally got my van scanned with a comprehensive scanner that gave me a printout of what the engine was doing when it was happening. The result: Defective Crank Position Sensor. Makes sense, the replacement sensor is in the mail and I should be able to tell all of you if this is in fact the...

There is a single ground-strap point for the entire coil pack and is located on the front right mounting point. As for the location of the arcing, it is definately coming from where the #4 plugwire mates with the coil pack. That connection is tight. I even replaced the plug wire with a...

Nothing out of the ordinary with the electrical system. Well it's Christmas Eve here in Hawaii and I'll think I'll take a break from this car until the weekend, time to enjoy the egg nog. Have a great Christmas everyone, see ya on the backside!

I was thinking the same thing but what are the odds of two coil packs going bad on the same cylinder?

Switched out #4 and #5 spark plugs and problem persists. I'm totally dumbfounded.

Update!!! Okay I think the problem is back with the coil/spark. I found out where the ticking sound is coming from. A spark is jumping from the coil pack to the spark plug boot. Occasionally the spark will find it's way to the spark plug (hence spark plug isn't wet with gas). But the...

I've replaced all wires including the plugs. The ticking sound is coming from somewhere around the coil pack. The engine is transverse mounted. If you're standing in front of the van looking in at the engine compartment, the number four cylinder is the front left spark plug location. The...

A stuck open injector...that could very well be the problem and could be the reason for the excessive MPG loss, averaging about 150-miles per tankful. So with a stuck open fuel injector sending unburned fuel down thru the hot catalytic converter, the possibility that this post detonation of...

I did indicate in my initial post that I'm getting spark and that it did use a coil pack. A coil pack is one module with individual coils for each cylinder, hence it is called a coil pack. A typical ignition system consists of a single coil, coil wire, distributor, spark plug wires, and spark...

I kinda figured it would be a defective fuel injector, however like I indicated in my initial post, I don't know how to get to that particular fuel injector. Both the injector and the fuel rail is buried under the intake manifold and at that point is beyond my abilities. The curious part is...

Okay I never got a response in another thread so I'm reposting my dillema here: -------------------------------------------------------------------------------- Hi I'm new to this forum and have been addressing this problem with my 2000 MPV Minivan with the 3.5L V6. I went to Checkers and...

Batteries will do that. I had a similar problem with a VW Scirocco once with a factory battery. Worked great. Started the car, kept the lights on, rocked the subs. Stopped at my destination, restarted after 5-minutes...battery dead. The cells shorted out so even a jump wouldn't keep that...

Hi I'm new to this forum and have been addressing this problem with my 2000 MPV Minivan with the 3.5L V6. I went to Checkers and they plugged in their scanner. I can't remember the code but they indicated cylinder 4 wasn't firing. Incidently there was a clicking sound coming from the area...
