Sluggish Celica, Check engine light on too Options

[Tru_Pol]

Ok, I bought a 95 celica ST with 70,000 miles on it for 500.00 bucks sometime ago. I have installed a custom cold air intake, racing plugs, wires, and a new cap. I have removed the 1st cat and hollowed it out (so if I get pulled over I can show its still there) and have a B5 bomber muffler. I have also just installed my bullet fenders (painted too). I have alot more planned but have run low on cash.

Now my problem.......My check engine light has come on and the car seems to run sluggish. It seems to take a long time to get the car to move. Does anyone have any ideas what the problem might be? Im thinking it might be a clogged fuel injector, or fuel filter. Any ideas would be great!

Sounds like you're in "limp" mode caused by a faulty O2... does the tail pipe suddenly spit a LOT of black smoke? If not black smoke... at least a lot more soot stains than before? If yes is the answer to any of those... it's most likely a faulty O2 sensor. I doubt it's the fuel system. That has other noticeable side-effects.
