It's probably missing... fouled plug, or otherwise
bad cap, rotor, secondary wire. Do a tuneup...
save the plugs in the order they came out, so
you know which went where... hell, your Haynes
has a decent chapter on this.

If it *still* misses, then look at injectors... pull
the injector wires one at a time until you find
the one that doesn't change the idle... there
you go.

How is the clutch on the fan?

Is the serpentine belt wearing ok? If it is getting any wear on one
edge, suspect the harmonic balancer.

It helps to know what was going on when this happened !! Did you just
walk out one morning and it started missing?
Was it just tuned up ? ect......

It could be a number of things. What accured ?



Inspect your plugs and cap. The way to do this without wrestling plug
wires is to wait until night ,fire the engine up and raise the hood.
look for arcing (fire jumping). make sure to check for cracks in the
spark plug insulators.

If it looks good you may have a vacumm leak , take steps to make
sure. Hose could have came off the breather ,carberator ect..
