My service engine light...

My service engine light came on. at 1st it was just flashing. Now its a on steady. I just had a oil change and radiator service

Mechanic's Assistant: Do you have the trouble code? Do you have a code reader or scan tool?

I dont

Mechanic's Assistant: Not a problem. You can work with the Chevy Mechanic to figure that out. What is the model/year of your Chevy?

However the coolant recovery tank was empty. its a 2003 chevy trailblazer

Mechanic's Assistant: Are you fixing your Trailblazer yourself? What have you tried so far?

I filled the gas tank thinking it could have been bad fuel and just filled up the coolant recovery tank

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I think that should do it

I'm not sure how to clear the codes

disconnent both battery cables for 5 minutes should clear the codes

if the check engine light starts flashing again it means the engine is misfiring and on these usually its a bad spark plug or ignition coil

it usually will set P0300 codes for a misfire

Also while I am at a stop, the engine shakes a little
Customer reply replied 10 months ago
thanks Gary

it sounds like the engine is misfiring usually due to a bad ignition coil for one of the cylinders or the spark plugs
