1997 Isuzu Trooper Question: intermitten check engine lite

Check engine light goes off and comes on and it seems to be related to when I put gas in the car. (Not always but too many times to be a coincident). Any ideas on how my putting gas in the car can affect the check engine light going on or off? -
Answer 1
The engine light alert you about a fault in the emission control system, the gas cap not closed properly could cause the Check Engine Light to go off. To better troubleshoot the problem I would recommend you to retrieve the diagnostic codes stored on your vehicle's computer. -
