1997 Geo Tracker Question: What is Evaporation System Malfunction and how do we fix it?

Can the service engine light come on because of it? -
Answer 1
Yes, the Service Engine Soon light will come on with an evaporative system problem. First you need to get the specific code, then a good shop can diagnose the problem. And, be sure that your gas cap is in good shape and is on tight with 3 clicks. -
