05' Avalanche w/ p0303 & p0353
My 05 Avy has codes p0303 and p0353 I have replaced all plugs, I have swapped the coil and wire from a known good cylinder The issue stays with cylinder 3. I have also swapped the injector from cylinder 3 with cylinder 1. Issue doesn't change. What should my next steps be? Thanks in advance
