Matthew came in with this vehicle running terrible. It was misfiring on all cylinders. We repaired a few vacuum leaks - which we did at no charge - and there was still an issue. We determined that we needed to check the spark plugs. I called Matthew and told him what we needed to do and gave him an estimate under the assumption that everything went good. His 04 Ford F150 with 171,000 miles had the originial spark plugs in it. It also has the famous 3 valve engine where the spark plugs break off in the head. I explained this to him and he said proceed. Three of the 8 plugs broke in the head. We spent three days trying to remove them - which we eventually did - and I called and informed him twice each day what was happening. I charged him 150 extra for our time to remove the broken plugs - which I had told him about. The Truck ran perfectly after. We appreciate your business and are disappointed you werent happy. The price was extremely fair considering all of the extra work we did and informed him of.
