I'm sorry to hear that you were unhappy with the service that was provided to you. I reviewed your file and found that your vehicle came in with a loose distributor due to someone throwing parts at it. We were able to replace the damaged components and get the ignition system working to find out that the vehicle had underlying problems that someone had been attempting to correct. At this point we continued diagnostics free of charge to find out at your fuel pump was not pumping fuel due to a poor quality install which we have documented pictures of we'd be happy to share with you. Due to this we had to special order a pump with the required hoses in order to properly repair. This is why we took the extra couple of days during repairs.
The low idle your experiencing was due to the distributor in your vehicle being one tooth out and at over 40 degrees advaced at idle. When we set this to factory specifications of 13 to 17 degrees the idle was lowered due to this. Any misfires could have become more noticable.
Once again we are very sorry that you were unhappy with the services you recieved but hope that this clarifies why we took so long and why you are experiencing a difference in the way your vehicle runs. It is very difficult to work behind someone that doesn't repair something right!
