1995 5.0 Engine Hiccup
I own a 1995 GMC Sierra 1500 with the 5.0 V8. The truck only has 12,400
miles and has had consistent maintenance under my ownership. There was a
slight oil leak that turned out to be coming from the real main seal and the
head gasket. When I drive it on the highway and step on it a little bit to go from
60 to 70, the engine hiccups and cuts out for a brief moment and gives a little
shudder. At city speeds, it's not really a problem unless I step on it, too. Does
anyone know what this might be and how I can go about diagnosing/fixing it?
Thanks!
