Laura-Rose’s truck hit 90,000 miles so she decided to switch to Super Unleaded gas. After 6 months, she didn’t notice any big improvement, so she witched back to Regular. 1/2 mile after the first Regular fill-up, the truck began to shake and buck, and stalled she took her foot off the gas. She went back to Super, but the problem is still there. Tom and Ray say the gas switch has nothing to do with the problem--just a coincidence. She likely has a bad distributor cap, and is only running on 3 cylinders.
