i recently noticed that my truck started idling weird like it idles really low then idles about 600 then back down and it seems to only do it when the truck is at normal operating temp but when the truck is cold it idle's perfect at 750 plus the truck has been using some oil like maybe 1/2 a quart in 600 miles or so and the truck just doesn't seem to run that good like it sounds healthy it just don't perform that well. it seems like it takes forever to get going. plus its only getting about 12.8 mpg i figured out and i run 89 in it. if anyone has any thoughts about this let me no

 

Yea most likly it is. To make sure just take your airbox off and look in your throttle body. If its oily, than its time.

 

^agreed

 

Your plenum gasket is blown, its blown on nearly every one of the 1,000,000 Magnum engine 1994-2001 Rams built. That is old news.

You should check and clean your throttle body and IAC sensor.

 

And the cat is toast or at least not too far behind.

 

yeah i figured that would be it ill have to order one soon from aps and get it replaced hopefully it helps and my cat is knocked out so that shouldn't be a problem and i look at the throttle body and it did have some oil on it from anyone's experience would it be better to get something from aps or just buy a m1 intake and get read of it completely?

 

Just get the APS kit.

 

m1 intake is about $600.
hughes or aps plate is about $150.

no contest.
