Ok ive got a 98 ram 1500 slt with 5.2 auto. the truck has 70k on it and every now especiall once its warm on a take off it loses all power on acceleration and has a pop coming out of the exhaust and you either have to mash the gas pedal to get it going or let off the gas. I cant figure it out theres no trouble codes ive got decent plugs and cap and rotor are ok any ideas???

 

clogged cat maybe? it's definitely not breathing right.
