Idle problem on a 1993 acura legend
1993 Acura legend check all sensors o2 sensor, mass air flow (may not have it) and maybe perform a tune up. plugs wires fuel filter and such. if it is still having an issue you may have a slightly different result. other questions is it only when cold or when warmed up too? does it throw a check engine light? does the outside temperature have any effect on it? Have you checked your fluids? do any fluids seem to be leaking?
