RJ uses Lucas Fuel Treatment in his 94 Toyota Ex Cab 4X4

I have a 94 Toyota that I bought about 3 years ago and

it has always had a rough idle and pinging in high gear even after replacing plugs, wires, cap, rotor button, etc.. and I have tried just about every "fuel injector cleaner" on the market

and I had just came to the conclusion that I would just have to live with it. Yesterday I went to the new Napa store in town and I saw your fuel treatment and I decided I would try it, and before I got home (less that 20 miles) I could tell a big difference in power. When I got home I left the truck running, popped the hood and I could not believe my ears!!! It wasn't skipping and it was quiet!! GREAT Product !!!!
