I am sorry that your truck needs more work than you were willing to do, but to be fair, you DON'T have the same problem you came in with. Your vehicle (with more than 200,000 miles on it) had several issues and multiple engine trouble codes when it came in. As well as an extremely dirty intake and a fouled throttle body, due to lack of maintenance. So the $700 you spent included those issues mentioned above along with diagnosis and us addressing the oil pressure problem. We discussed this with you and you approved all of these things. We would have loved to have resolved the oil issue as well, fortunately that issue needs further work.
