miss on #4 cyl

Possible burned valve, failed head gasket, lifter failed. We had a miss in #5 cylinder on a 99 Tahoe, turns out the head gasket failed. Had Spark, Fuel Ect.

i had the exact same problem. a misfire on #4 and tried everything to fix it, get a compression test quick. i had a blown head gasket and ignored it, next thing i know BOOM #4 piston chipped off, $1,300 for a new engine.
