Lean/Rich related Could be too much or too little fuel, or too much or too little air. So it could be a MAF, or bad o2 sensor. Stucky, or leaky injector, off ignition timing, or even a misfire,
I think if I were you I would-Check the plugs, wires, cap and rotor. If not new, I would replace them,-Set the timing correctly (timing light)-Check the EGR, and all vacuum lines for leaks (unmetered air)See how it runs. If its still off-clean throttle body, IAC, and pull the injectors (soak the tips only in seafoam) reinstall with new O-Rings-Clean MAFSee how it runs. If its still off-Try to borrow, or get your hands on a new MAF / o2 sensor
