paseo missing?? sputtering

[aj1978]

Ok guys need some help here. My paseo starting acting like it was missing. all rpms, all the time, big lack of power. Did a tune up, plugs, wires, cap, rotor, fuel filter, coil. Still doing it. Should I check fuel pressure next, or does anyone have any ideas. There is about 205,000 miles on her and I'd really like to go more. Thanks, for the help

Yes I would check fuel pressure, No check engine light? how about the O2 sensor? when was it changed last. injector cleaner? Try sea foam through the intake. NAPA sells the seafoam, disconect the pcv hose and stick it in the can while running suck up 1/3 of the can and shut the engine off let it set for 15 min then start be whaite smoke for a while but it cleans the cylinders and valves real good. put the rest of the can in the tank to clean the injectors.
Could you have gotten bad gas water in the fuel.

just got a chance to look at it again, one injector was way off on resistance, replaced it fixed>>>>. nice forum though I'll keep in touch
