b16 heats up and loses power

[reckl3ss]

I have a problem, I have a 92 bubble with a b16 swap and, when I turn on the car and run it while its cold it is totally normal, but when I drive it for a little and get to normal running temperature, I have barely any power. when I shift in to first and try to go a quick it just accelerates as if I was driving normal. it is weird because the engine still revs high when i step on the gas, just the acceleration doesnt match up. I have a rattle in my catalytic converter that is getting worse, I dont know if that could be the problem. any ideas?

Clog in the exhaust could lose you power like that, I'm really not too sure what else could be causing power loss when your at operating temp.

A plugged cat and a slipping clutch.

Good deal, a free and easy fix.
