Misfire and ticking
Haven't had truck over a year out the blue get a flashing
CEL scan came up cylinder 7 misfire change all spark plugs
coil packs a full tune up still when I try to hard accelerate
CEL start flashing again and begins to run rough at low
speeds truck drives fine dont want to keep spending money
on stuff that ain't fixing the problem truck been sitting a
month now. Any answers also start making ticking noise.
