I am the original owner of the above car and have always taken care of it;

Best find one you trust...many good ones exist. Most people fear what they don't know. Mechanics are no different than than any other type of work. Many are very good and are professional...a few are not. Suggest you get recomendations from friends, coworkers for s good technician or shop. Look for ASE certifications and other affiliations like BBB. My guess your car is exspericeing some normal wear and tear issues. Below I have listed the potential causes for that fault code: Potential Causes Low Engine Oil Plugged Oil Passage Insufficient Oil Pressure Plugged Oil Screen Insufficient Oil Volume Defective VTEC Solenoid

if you stop the engine and then turn the key to ignition on doe the oil light come on ? how old is the car ,how many miles has it done ? does it have an oil leak ? or is it burning the oil ? has any one checked the oil pressure switch ? As for a rough idle any mech should able to see what that is , these cars are complicated ,i own one but do my own work What you need to do is go to you tube and type in honda accord you will see a lot of vids on there and a lot of handy information , down load everything you can and put it into a file and check out out problems you may get .
