ok i have a 01 alero with 80k miles. basically it revs fine motor runs strong in neutral and drive, no misses or anything. as soon as i put it into gear it accelerates really slow and i have to let off the gas to get it to shift into the next gear, it wont go past 4000 rpm in any gear and maxs out at like 45-50 mph. i thaught the cat might be clogged, and had a backpressure test done and there is alot more back pressure then there should be. i dont have the 300 bucks for a new cat, can i just gut it out?
