I have a '87 D150 with 318/auto 2bbl
I have installed new plugs,wires,cap,rotor,temp sensor,and EGR valve. The truck seems to run well on the road,smooth that is. I do feel a slight miss/fumble during idle after the truck has warmed up. I checked around for obvious vacuum leaks but haven't done any true vacuum testing. Any suggestions on where to start looking for the cause of this miss?
