Well.....long story short, took the car in for check engine light being on, air conditioner not working and for a oil change. Picked it up the next day, paid $650 and drove about 1.5 miles and the check engine light came back on. Took it right back to the shop and since they had our other car in for an oil change they told us to bring it back when we picked up the other car, in the meanwhile,we got the car home, checked under the hood and found oil blown all over the engine, 4 bolts from the valve cover were loose and had to be torqued down. When it was time to pick up the other car the check engine light was already off, we left the car anyway so they could go ahead and fix the problem, but apparently what we did fixed it. So......just makes you wonder!
