Please Help........! Sorry in advance for the long question: I have recently bought a 2000 trooper.
My check engine light recently came on and am wondering why? I get 12 miles to the gallon ( after bringing to dealership for the emissions system cleaning ). How do I clean my erg valve? I am very unmechanical, is it something I can do? The tail pipe have a black powder on the inside ( assuming oil, not greasy though ). How do I change my pcv valve? HELP PLEASE!!! I travel 90 mile round trip and at this point it would be cheaper to take the helicopter to work! Thanks for all the help and appreciate it 120%!
