Thank you for your review. I am sorry that your vehicle is still having issues. When your car arrived on 6/20/17 it had a missfire on #3 cylinder with a stored P303 cyl 3 missfire code. During this visit we replaced spark plugs and a #3 cyl ignition coil. You then returned on 6/23/17 stating the vehicle was running hot at that time we replaced a coolant thermostat and road tested vehicle with no concerns. You then returned on 6/29/17 complaining of bad fuel economy and check engine lamp coming on and off. At this time we scanned the vehicle and found no problem, no diag codes. Not even history codes, we asked if you could leave vehicle for further diagnostic, but you were unable. We did address the issues you came to us about, you did not mention on your return visits of still having issue of overheating. We did give you a can of seafoam and asked you to try it regarding your fuel economy and to let us know if you have further issues. If you are willing to drop off your vehicle to get further diagnositcs regarding these issue we are more then happy too. But please know we have done all we could at the times you were at our repair facility and feel we had resolved the stated issues at that time.
