I have a 1997 ram 2500 with the 5.9 in it. The truck idles like a brand new truck but when i give it any gas it bogs down any bearly stays running. I already did the idle air control motor (i think is the name) on the back of the throttle body and i also did the throttle posistion sensor. But it runs exactly the same. If anyone has any suggestions it would be greatly appreciated. THANK YOU!

 

is there a difference between when it warms up and when its cold?

 

Thank you for your response, but i did just fix the problem...dont laugh...it was a plugged cat. converter. It runs well now, unfortunatly i just broke a spark plug off in the block Only good thing is that it is my works truck and not mine, haha thanks again.

 

How much did you pay for your tps?
