Why after installing new plugs, plug wires and a new ignition coil. Why has my miles per gallon dropped. The work was done by Firestone and they lost a customer for life. I consistently got 18 to 20 MPG before they performed a major tuneujp.
Do you

When they did it, did they use quality parts?

Now is the time to further explain the "Big Picture". I do not like Firestone but my truck began running really rough on a Saturday night so after attending church at 1030 on Sunday, I took my truck to the Firestone Service Center in Brandon, Florida, arriving at 1233 PM. The check engine light was flashing. The service rep went with me outside and I showed him how the engine was running. He said he would run up the invoice later and since it was a Sunday and I wanted to watch the "Bucs" game at 4 o'clock. I was offered a Winter Check-up for $9.99 so I accepted the offer. 45 minutes later, a mechanic grabs my ticket off the counter and goes out and starts the engine and shuts it down and puts the ticket back on the counter. I check with the service rep and he informs me that they have to run a diagnostic check which will now cost me $99.99 so before my truck is even in a service bay, I am already obligated for $125 (rip off #1) after adding Uncle Sam's take. I informed the service rep that I wanted the mechanic to order whatever parts were necessary to correct the problem. 30 seconds after doing the diagnostic, it was determined that the ignition coil was shorted on clyinders 2 and 4. The hair on the back of my neck was starting to rise. The mechanic orders the parts. The main service rep was on the phone almost the whole time I was at the service center and the junior service rep finally decides to run up my invoice. The mechanic recommends that I change the plugs and the plug wires and I agreed with the explanation. After the junior rep completes the invoice, he shows it to me and to my unpleasant suprise, the total bill comes to $667.00 (rip off #2). The job is completed and I paid the bill with a credit card but that is not the end of the story. After doing some calculations, I determined that Firestone charged me $16.42 a plug and $13.14 a plug wire which I know come in a set. I then called Brandon Ford and asked the parts department how much would a new ignition coil would run and found out that Firestone charged me $32.00 more than the dealer cost is. I was highly agaitated and went on-line to Firestone and filed a complaint. I was contacted by the district manager and I expressed my dismay over the cost of what they said was a major tune-up with a 12,000 mile warranty or 1 year. He agreed to redeem back $175.00. I informed him that Firestone had lost a "customer for life" and I would never use them again. I received my check right after the XMAS holidays. A month later driving to work on MacDill AFB, the engine began running rough again and the check engine light began to flash. I called the downtown Firestone Service Center and told of the situation and they agreed to take my truck in that day. I arrived at the service center and low and behold they found that the previous work was faulty because the mechanic failed to route the plug wires through the cradles properly and a plug wire fell on the manifold and burnt through the rubber to bare wires and of course it was shorting out. Two hours later after the plug wires were replaced at no cost to me, I was able to drive back to work. Since that time my mileage has been lower than normal so to answer your question, I do not really know. Where Firestone got their parts I have not a clue. Again I state, Firestone has lost a customer for life and I would never recommend them for any vehicle repair, not even a headlight, which they could not fix because they did not have any in stock at the MacDill AFB Firestone Service Center when I was driving home one night. I had to go to Tires Plus to get the job done for a very common headlamp. Best said, is that Firestone is a major rip-off center rather then a service center as adverrtized.
