I'm 5'4" and I roll around town in a big ass monster truck...Ford Excursion Diesel that is! After many trips to the Ford Service Department and leaving with no explanations or problems resolved I became rather frustrated and in need of some guys who could get the job done right, the first time! I began doing my research and came across these guys. Yes, there is one man who has left a one star review (in more places than one) but if you have ever been to AJ's and met John (the owner) and Mark you would know that the mans story is a little hard to believe. My husband and I frequent this place and have never had an issue. John is so great and knowledgable and he always does a great job. I came in with overheating issues that Ford could not figure out and AJ's had it diagnosed in an afternoon. We ended up having them bulletproof my excursion so we could eliminate issues in the future. It was the way to go and my truck has been running great ever since. I brought it in another time because I had a loss of power and Ford just kept replacing my fuel filters (they never examined anything further). AJ's pulled my gas tank and found that I had algae growing in there. They took all steps to remove the algae and now my truck has more power than ever! Vroom vroom! I also have them do all of my oil changes. If you own a diesel you should seriously check these guys out!!
