My truck started smoking white (unburned fuel?) and missing, So I used my had to rev the throttle under the hood while watching the exhaust to see if it would clear with a little rpm. I was probably at about 2000 rpm and heard a pop and then a loud bop, bop, bop, coming from the intake with each revolution. Intake valve was my first thought? What kind of damage would a leaking injector do that would cause a back firing through the intake? Trying to decide where to start.
