You look down the thru the throttle plates, while holding wide open, with a flashlight, not running, of course. To do that, you only need remove the clamp holding the air tube, and move it aside. Oily bottom = gasket change, which I suspect you have awaiting you. I had a #1 and #8 misfire, the sensor detects the associated vibration & references the crank position sensor, to set codes, apparently. when mine went, I could keep the codes away by running , temporarily albeit, by disengaging overdrive.

^ what he said. Removing the intake should take like 5 minutes if that.

Default Same Problem Here

I had the exact same problem and changed the Tranny which didnt fix it.
Changed plugs and no wires. u really need to change those wires. My truck shuddered on the interstate at 70mph very bad and not as bad in 3rd at 45mph but it was still a shudder none the less. I changed Cap rotor pulgs and wires and it stopped. to find out if it is your wires, wait till dark where it is pitch black when u look under the hood of your truck. Start the truck and look for a arc or a spark traveling outside the wire or where the plug meets the distributor cap. If you see blue then you need to change the wires. I had a fouled plug and man was it filthy when i pulled it out which i attribute to a valve cover leak. When you took your plugs out what did they look like on the sparking side?

Changed the valve cover gaskets and now a slight shudder has came back.

Does anyone know how a plug keeps fouling out. If i ran a missing cylinder for awhile till i fixed it, when i put a new plug in should i have sprayed something in there before replacement?

EDIT: Oh also my repair manual doesn't mention a plenum gasket, does it go by another name?

Thanks for help all!

From what I understand the original plenum and plenum gaskets on these trucks were poorly designed. It's not a question of if, but when, they will fail.

The gaskets, yes. The pan, well, I've never seen a pan cause a problem. Hughes came up with a great "repair" by offering these kits. Wish I had thought of that.

My 01 Ram issues started out a month or so ago. It began accelerating roughly at higher speeds – it had just ticked 100k miles so I figured it was time for another cap/rotor/plugs replacement. This was approaching hunting season so I kept putting it off as I didn’t have any time for it (or didn’t prioritize is more honest). It shook a bit when accelerating uphill, or at higher speeds especially in OD – mostly in around the 1500 RPM range. I found that turning OD off and/or gunning the engine a bit up to 2500 RPM or so eliminated all symptoms.
By the time I changed the cap, rotor and plugs (which had zero effect) the shuddering was a lot worse – then engine light is always on now, and when I rev the engine to get past shuddering now, the light starts flashing which, according to the manual, means my truck is about to commit suicide with me in it. With OD off I can maintain about 50-55 MPH but OD on is constant shuddering. Don’t get much shuddering in 1st or 2nd but it’s becoming more pronounced in 3rd and 4th. Cannot drive faster than 55 MPH without either the flashing check engine light or the shuddering.
I found a similar problem posted on here recently but that one seemed a little vague, thought since I had all these little details it might make a difference. Can anyone help?

2001 Dodge Ram 1500 Quad Cab 4x4 5.9L Magnum V8 with 103K miles
Installed a Spectra air filter assembly about 4 months ago; everything else is stock
When I replaced the plugs this month I used those Bosch Champion 4+ that supposedly don’t need to be gapped, for what that’s worth.
My dodge Ram 2001 5.2L Automatic exemplified the exact same symtoms as described by spadams.

This morning I replaced plug wires, Distributor Cap and Rotor and GOOD TO GO!
I wish no-ones problems needed more attention than this, but that was all it was for my truck. By God's Grace
