i just did a tune up to my truck about two months back plugs cables cap, rotor, and fuel fillter. i have also replaced the cadalidic convertor. now my truck is putting and back firing and wont drive at all. i ran a code test and it picked up multiple/random cylinder misfire. i then checked a couple spark plugs and none were fouled. coud this be a bad injector?
