i have a 98 ram 1500 5.2. am running 33'' tires with 40 seires flowmaster and K&N CAI. before i had the flowmaster and the CAI and was running the 33'' i had plenting of power could pull anything with no problem. now after the up grade she dogs on me bad, has no pulling power at all. i replaced the cat about 6 months ago and took it to a shop to have them look in to it and they found nothing wrong with it. what could be my problem.

What did you change?

 

the air intake and the exhaust.

 

So, all you did was add a cai and a muffler and now you have no power?

 

yeah.

 

Few problems.. fix the plenum. Clogged cat. Flowmaster is restrictive. Stock gearing

 

I would try unhooking the battery for awhile. Let it relearn the idle and all that since you changed your intake. Maybe that would help? Can't see why just adding a CAI and a muffler would make you lose power, unless....your plenum just **** the bed.

 

ok, i have reset the computer, didn't do anything. all check the plenum.

 

is there anyway to clean the plenum with out taking it a part?
