2001 ford f150 harley edition 46000 miles 5.4 engine. I noticed a jerking or shutter as they call it around 40-45 miles per hour. I took it in to a shop and he told me the computer said there was a misfire in #3. He said I had a bad wire and changed all the plugs and charged me $250 bucks. The truck is now worse. He then told me it was a transmission problem. Over the phone a transmission shop gave me an additive to the trans fluid called "shutter fix" but that did nothing. After I had brought them the truck they told me it was a msifire at least in 2 cylinders. Can someone tell me what might be going on and why did the first mechanic not fix it by replacing the plugs and 1 bad wire according to him. Any advise on what to do next? Thanks
have the same problem?
