Chevrolet Carlo LS: I have a 2002 monti Carlo that has

Customer Question

I have a 2002 monti Carlo that has no pick up it bogs down every time you step on the gas to much. Also the rpm won't go over 3500? I've changed the fuel filter and the EGR valve. There are no codes coming up. The EGR was a code but replaced that. Any ideas?

good afternoon my name is ***** ***** I will assist
2 things come to mind.
1. check the fuel pressure. low fuel pressure will do this
2. clogged cat converter. do a back pressure test on the exhaust. that will tell if the cat is clogged.
