Having problems with your 2003 Mitsubishi Galant ?
My car is putting and check engine light is on. Didnt know i suppose to use premium in an ES model. Will using 87 regular cause this problem or could it be a tune-up?
Check ur fuel injecters
When was the last time you did a complete tune-up? it could be a couple of problems, like a fouled spark plug, bad plug wire, or the distributor cap and rotor could be worn. your owners manual will suggest what grade of fuel to use. the 87 is the amount of octane in the fuel. the more the octane, the better it burns. if you haven't tuned the car up in at least 3 years, do it. while doing that, check your belts and hoses. 3 years or more, rubber does wear out under pressure and heat. while tuning up, don't forget the fuel filter, save your self a big headache later. hope this helps
