my 98 dodge ram 1500 4x4 runs like a rapped ape is there a way to know is it had a tune to it or not? hate to spend money on a tuner to only find out its already been done

 

Doubt it lol , you prob don't have a blown plenum yet yet .....

 

ok i havent figured out how to use the site yet buy i am haveing a problem with my 95 1500 the problem started out that my truck would not get over 55 and had no power and when i gave it more gas it the speed would drop. then it went to it would not get over 35 and if i let off the gas it would die and if i gave it gas it would stumble. so i figured it was the cat and i just bilt a new exaust from scratch i didnt put a new cat in i just left it off and put a muffler on so it started running ok a few hours but i can smell gas like the engine is running ritch and it is starting to die at low rpm now i left the o2 sensor off could that be my problem? and could it have been bad in the first place? i know now i have the 51 code?

 

Ya I would replace o2 sensors with ngk

 

The cat was most likely clogged, because of the blown plenum. Which also ruined the o2. In any case, it needs the o2's. But I'd make sure the plenum is not blown first. Before ruing perfectly good o2 sensors again.

 

Thats what i thought thanks for the help

 

hey this is my thred
