I went from a cylinder 5 misfire pulled my plug and Gap was about .06
put fresh AC Delco plugs in there then I ended up with the multiple cylinder misfire.that went away and then it was just a cylinder 5 misfire then a few times there was nothing for a while. now almost anytime the truck is idling the check engine light flashes. I checked the compression. I'm 150 psi... I'm at 5200 feet elevation so so that's pretty good.. I'm suspecting the spider injection or something else. My fuel pump was replaced last year. My engine definitely runs rough at an idle. 2 years ago it was getting the distributor code after putting the distributor in but I adjusted it until it went away that was two years ago. this misfire recently started. I guess I should also point out that I have TBI Gibson headers and the EGR valve is is not hooked up. There are no emissions where I live. the previous owner deleted the catalytic converters.
Short of replacing the spider injection system I'd like to know what's wrong first
