Has the check engine light come on??? Go to a parts store light autozone or orielly's and get the code read, also look for pending codes. When has last tune up been done? Have you used any injector cleaner lately?? I have read most people say Chevron cleaner is the best. Has the upstream oxygen sensor ever been replaced?? How is the idle RPM, is it about 750 rpm? Have you cleaned the Mass AIr Flow sensor lately??
Another thing to look at is the camshaft sensor or optical sensor in the distributor. Take the distributor cap off, rotor and cover over the optical sensor and look for a brownish dust on it. Use compressed air and blow it off. IF there is any of this brownish dust check the distibutor shaft for looseness. bad bearing?
