[QUOTE="Bob Floyd, post: 1010991, member: 70385"] Uncle Bob, your spark plugs are Junk! they are way over due, Not to mention going to be a lot of fun getting them out. One of my many jobs at FOMOCO was a powertrain calibrator, Spark plugs begin to fail badly at around 100k its a wonder you can even get it started on cold days. The required voltage to fire the worn plugs is getting near the max your coils can put out. Your fuel mileage is getting much worse and your emission's are very high, hydrocarbons' are through the roof. Spark plug wires are good for two to three years then they begin to fail and leak voltage. Get a good tune up change your fuel filter and you will think you have a new trac.. [/QUOTE]
