I have a 95 Escort Wagon with about 160k miles on it. It's been extremely reliable, but recently it has developed a hesitation problem. It happens periodically, particularly after a downshift (its manual). My first guess is its the plugs. I replaced the plugs maybe 1.5-2 years ago with Bosch Platinums. I pulled them out and they look like they are in decent shape, but not perfect. Is it likely the plugs or should I suspect something else? I don't mind plunking down $6 for new plugs, but I'd rather not play guess and check with a $100+ coil pack and half a dozen other things.
