Car has no power, help if you can

My car feels like it has no freaking power. I can punch it in 1st and it barely picks up. It feels like the clutch is gone, but I don't know. It still shifts, doesn't grind or anything, but it feels like it is gone or the cats are clogged.

Before you ask, I havent' checked the timing (no light) or the fuel pressure (no guage), but I know it is not right.

Anyone want to try to diagnose something over the net?

LOL

I would think about tuning, but it started running like this all of a sudden. feels like it is choking up (has a K&N) and I just changed the fuel filter. I get a little bit of what sounds like a slight backfire when I stab the throttle up to 2k and let it come back down.

It is waaay too hard for me to explain, I guess I should just forget it. Oh well.

Just some bad gas. I feel so dumb sometimes--just overreacting like a new daddy with his kid

Thanks all

Well looks like I counted my chicks before they hatched. Car is still running bad. It has decent power, but seems like it is choking. When I hit the gas and rev it, it backfires a little. I changed the O2 sensors, but that did nothing. Looked at the salt & pepper shakers on the intake, they look fine. I cleaned the IAC, no go.

I was standing behind the car while it was running and I could hear the pump working--I was 6-8 ft away, too. Is this normal? I don't think so, but I could be wrong.

I don't have a pressure tester or a timing light, so it looks like I either wait or take it to a shop to see if they will diagnose for me.

Oh yeah, the previous owner(s) of my car decided running codes wasn't important and cut 2 wires to the test connector---one so close I cant even re-do it. I have to scrounge up another one.
