Add the middle grade gas to tank and a bottle of Lucas Fuel Injector cleaner to gas tank.


I will give this a shot and let report back. Thanks.


Still the same problem after adding Lucas Fuel injector cleaner


Take vehicle out on road and hit the passing gear a few time this will help clean out the gum and carbon build up. Also check air filter.
