Hey everyone,

have a new optima yellow top on my 97 accord, and also a new alternator. However, at least twice a week, my car will start up very weak and it will vibrate somewhere near the engine.(almost seems like the car wont stay on as well) Also, everytime i now start it theres a screeching sound.Checked all the belts and they all look fine.Other times the car starts up normal and not weak at all. Could this be a sign that the starter is going bad? Already tested the battery and everything looks fine.
