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?
