ruff idle

My baby is a '92 and it is in terrific mechanical shape, but it idles a little hard, jerky, ruff, loud, etc... is there anything to significantly calm this down for little cash? If not, what major things can be done?

Thank you.

Have you tried changing the plug and wires? When's the last time your fuel filter was changed?

Fuel filter is probabily not the cause here. Even if 50% blocked it will idle fine, won't run very well on the road though. Idle on cars can be affected by:
1. A dirty/sticky IAC valve. Cheap repair- remove and clean with carb cleaner. also clean hole.
2. A dirty fuel injector. Cheap repair-sometimes can be removed and cleaned with carb cleaner.
3. Vacuum leak-find and replace hose or gasket.
4. Replace plugs. cost 4$ or so.
5. Wires could be helpful. Cost under $20

There are other things but these are the cheapest and most common I could think of. Good Luck.

Thank you much, I'll try all of the above.
