Do we have a forum for non-BMW problems cause I didn't see a better place to put this.

I also have a 95 Rodeo 3.2L that's got 120k miles. It was my first car, also my backup car now.

I know there are probably a lot of answers to this question about loss of power but here goes: my Rodeo is making a lot of hissing noise underneath when hitting the gas - also sounds like I don't even have a muffler - loud exhaust (actually loud even at idle). Probably a hole in the exhaust pipe after all these years of road salt, etc. - I can hear the noise echo off barriers and other cars as I drive by. Is this alone enough to cause loss of power?

I hit the accelerator like I used to but it's just not getting the same pick-up... takes forever to even get to 40mph from a red light if you know what I mean. Could another part underneath be damaged - catalytic converter contribute to power?
