Hey Scotty.
Had a misfire issue, checked plugs, gap out on #2 and #3 cylinder. I replaced them, ran well for 2 weeks and but then back to how it was. Misfiring, but mainly in third and fourth gear, when trying to increase throttle quickly.. Pulled the plugs back out, gap was out again. What would cause gap expansion on new plugs so quickly???
Vehicle is a 2002 Toyota Hiace 2.4l petrol (RZH113r)

a rich mixture
Caused by a leaky injector??
could be that. Could be faulty MAF /O2 sensors.
