I bought a high mileage diesel truck (my first diesel) from an out of state dealer.... ""as is"". That tells you everything you need to know! ;) So, what I did not know before, I am learning now... and one of those things is that knowing about gas engines is about as useful to diesels as experience in fast food is to fine dining! So, with that said, I looked online to find a diesel shop with good reviews to deal with the ""issues"" my new POS came with! I am glad they did! Jesse and his crew did an excellent job, fast and for a very reasonable cost. My repairs would have broken the bank had they not worked with me on finding good used fuel injectors and in repairing (rather than replacing) my faulty Injector wiring harness! (saving me around $600!) Needless to say, they will be getting my business the next time something I can't fix fails!
