Sometimes the engine idles at 3-4 thousand rpm, other times it barely idles. Fuel is not being used efficiently. It is totally unpredictable.

What car?
I can almost guess. 4wd, Sidekick USA or Vitara?

93s come with 8v TBI or 16valve MPI fuel injection.

Which one you have?

This old car( just sold a 91 I restored to like new running wise)

lots of things can cause that.
I could list off all 100 of them, but no.

Is check engine lamp on running? #1 top thing.

Top fails.
1; horrible need for a tune up. Wires cap sparks and filters
2: EGR stuck wide open (main valve)
3: CRACKED exhaust manifold.
4: bad o2 sensor.
5: TPS bad or not calibrated (tps switch must close on this car or car will NEVER idle right)
6: gummed up ISC valve.
7:ECU capacitors in side bad, "Rubycon" desease.

I could give more and some tests but you didnt give car spec.
Please post back you are very welcome.
Cheers.
