2000 zr2
So I have had everything done to this truck tune up plugs
new gaskets o2 sensors said had a misfire on cylinder 4
cause of power steering pump leaking oil on sensors so
got that replaced and all sensors replaced and had new
egr valve I mean everything has been done to this but the
misfire left for about two days but just left from eating and
it came back on got it scanned and said misfire on
cylinder 4 I'm running out of ideas it's a 2000 Chevy s10
