FOULING PLUG

Dodge Ram

I have a 2002 Dodge Ram 1500 4x4 quad cab with a 5.9L motor here is the deal about every 30 days my check engin light comes on and the code is miss fire on #8 cyl. If you pull the plug it looks good (not oily or burnt ) but its dieing more each day after the light comes on intill its running worse and worse soon as you change the #8 cyl. Plug it starts running great again shortly after that the light go out. I have taken it in to the dodge dealership here in las vegas but they do like the corner repair shop and just kept changing parts out but never fixed it I need real help now. They serviced the carb checked the injectors and checked the elec. System everything ok please help

Is there anything else that has been replaced?

What more can be told that we don't know about what was done or what other sypmtoms are there. Info is key.

If I understand this right, after you replace the # 8 plug, the truck runs fine?

The ONLY code is a PO308?

You may be right about the bitter part but it seems like every mec I meet ends up screwing me for a few hundred wait does that make me a trick well get back to that most of the time if I change the plug it starts running fine but not this last one I think I need another platuim plug they seem to work best. At dodge they said they changed the injectors around incase that was it also changed fuel filter

I am at work at the moment, but have some info that i'll post tonite. : D

Couple questions: how long has this been happening? How many miles since it started roughly?

How many miles are on the truck?

Are you losing any coolant. At all?

These answers will help as there are a few scenarios that I'll write about.

This has been going on for a year and a half
started about 31,000 miles
now there is appx44,000
I have never lost any coolant

Okay here is what I “think” is the problem based on the research I did. I would recommend having the intake checked for leaks as the leak from under the valley pan gasket is common. For as long as you have run it this way I further suspect that you’ll find a crack between the valves on #8 cylinder on the cylinder head.

I did a little more research on this as well to help you cross the bridge. Straight out I don’t know these folks from a hole in the ground, but they have tell tale signs that make me comfortable. They are a member of the IATN network, and that alone says your chances of success are increased. I would gladly contact them and bring them up to speed if you like. I don’t know them not have any benefits from recommending you there.

It is very important that you understand what is happening to avoid any bad experiences that you have already had. Be sure that communication is good between the two of you, and feel free to post any questions or needs. Good Luck!

Thank you for your time and effort.
