Get your fuel sync checked.

 

Not sure if you fixed your problem but I had the same problem the scanner keep sayn cat do I yried the NTKs an it went away but still got a rough ideal my MAP sensor is the last one an 00dakdan good to know I cant get rid of the brip even thou it bugs the hell out me

 

I have one of these 2.5 liter dakotas. It has the 5 speed manual with a 3.90 gear in it. (limited slip ive found) its a great little truck, but way down on power. Im thinking of converting it to the 5.7 hemi. Found the conversion kit with motor mounts and oil pan. Ive thought of everything i can do to it, yet essentially its not the best engine for the truck. anyone elses have a harmonic balancer scraping the timing cover. i best maybe 22 mpg combined
