Runs fine but hicups while idleing at a stop light. Check engine light does not come on. Have replaced spark plugs and wires. Put in new coil but it did not change so put old coil back in. Replaced engine speed sensor. Still have same problem.

Could be clogged fuel injectors, or it could be the mass airflow sensor giving it some trouble. There's a fuel induction cleaning service offered by many dealerships that will take care of the problem for you if that's the issue, and is a good idea to have done anyway even if it's not the root problem. Usually costs around $120.
