Your check engine light should be on. There is obviously a problem. The best course of action is to have the engine scanned for codes. The on board diagnostics should have stored one or more trouble codes, based on the information you have given. A good auto parts store will scan your computer for free. Any diagnosis at this point would be guessing, and not based on factual information. It could be anything from a bad sensor, to needing a tune up, to a plugged catalytic converter. Get the codes and let me know what they are and we will try to figure out a solution based on that information.

Have you got your car scanned?If not,then i advise to get it scanned at car diagnosis you mentioned that engine light gets on/off.So this engine light flashes when the computer(ecu) in the car notices any kind of problem.At car diagnosis center they scan the car and give you the error code as per the error code you will get the exact faulty part which is causing the problem.At its free to get car scanned.Or if in case your regular car mechanics have the car scanning tool then ask them to get it scanned for you.This will help. Thanks.Helpmech.
