Two things, have the fuel pressure checked, also have a PCM fault code test run with a code reader. Autozone and others do this test for free.

Did you clean the fuel injectors? these always happen when they are blocked.

plugged cat hmm'
if plugged there would be a power loss on highway or in city .
it specs will change during operations but if the dash light is coming on then the o2 sensor or senors is causing the variation readings.
the o2 sensors are responsable for monitoring and reporting these readings.they are exposed to highheats and these parts will give missreadings when failing.o2 sensors tell the computer to ad or remove fuel from the pulse durations.

sounds like a clogged fuel filter. you need to have the engine pressure checked for leaks, you can rent the pressure checker at autozone, it connects to ur radiator and u pump pressure into the cooling system if u find water leaking around the head u know u have a blown head gasket. if ok then check the cylinder compression should beable to rent this also. it screws into the spark plug holes has a gauge on it. alternator problem w/ the light is probaly you need to tighten the belt.hope this helps!!!
Testimonial: "thanks very much. i'll check that out."
