1999 Ford F-150: jerking or lurching

Filed Mar 29, 2011 · 132,000 miles · KS

I have a 1999 ford f150 that while driving down the highway at 70 miles per hour, the #3 sparkplug suddenly blew causing the truck to tremendously jerk. I have read numerous complaints of this happening and ford denying it is a issue with their motors. I cannot afford $800 that ford wants to charge me to fix a spark plug issue. I'm not mechanical inclined and do not know how to do it by myself. My truck has been sitting for 2 months because of gross negligence by ford motor company by not taking responsibility for an issue that clearly needs to be recalled and repaired before (if it has not happened already) causing death. Luckily, it was late at night and no other cars were near me when it jerked my truck so badly that someone clearly would have rear ended me.
