platinum plugs=fouled plugs=hesitation

Just wanted to let everyone know, finally found what was causing all my engine trouble, hesitation, missing, poor throttle response. Platinum Plugs, with a stock ignition system. I had been told it was a possiblity but as everyone knows the plugs are alot of work to get to.

Autolite

Autolite 3 year platinum plugs, real bummer. With costco gas they would foul out real quick, had been using chevron super and the car improved but continued to get worse and worse.
