1993 GMC S15 Jimmy - runs ROUGH after tuneup.
Ah ok. I JUST got in contact with the previous owner. They said the fuel injector and regulator were replaced about 15,000 miles ago by the previous owner.
That may be the reason that its clean in there..... or is 15,000 miles enough that it should be pretty nice and black all over in there?
(was really hoping to visually see that it leaked since with this new information its even more difficult to figure out.)

I wouldn't think 15,000 miles would be enough to make it nice and black all over.
Plug it in, pull off your coil wire (you do NOT want spark) and pressurize the system to make sure there are no leaks before you button everything back up.

I have not pulled the old spider out yet. But I have the one i got from the wrecking yard today on my shop bench.
But now Im not sure I even need to swap this out.... Since the previous owner said it was swapped out a little over 15,000 ago.
Since the one i bought from the wrecking yard obviously has a bad FPR I will take the FPR off my spider assembly and swap it into this new one and install it and see if it runs any differently.

UPDATE! just went to swap out the spider injector. as i was going to remove the pop rivet leg thingys one of them was already falling apart from the clip thing that you squeeze. so im betting very little fuel was actually making it into that cylinder. Will post an update once i finish swapping this out and testing it out.
what exactly is this "spider injector" you replaced... is it available at parts stores?? i believe my truck is having this same issue
