Have a 1991 Ford Ranger 2.3 that runs fine. It stalled sometimes when first starting...I decided to change the plugs and used the "gapless" Bosch type. Now the truck starts and idles smoothe BUT.....it now ha a "miss" in it. Kinda coughs and sputters a little when gas pedal depressed....could it be the type plugs I used or I'm thinking the plug wires. I don't think they have been touched in many a year. Thanks, gregg
