the spider injection leak would also make it run rough. you can tell it has a leak when, after you stop the car for a while after driving, it takes a moment to for enough gas to get in to ignite. almost like the sound of a carb bowl filling up. then it turns over. otherwise, check all of the sensors, the egr, the air intake, the oxygen sensor for carbonation and clean them. sometimes, that helps a bit...
after, disconnect the battery for ten to thirty seconds for the CPU to reset.

What are signs that you have a bad EGR valve in a 1997 Jimmy Vortec V6?
The signs that I had were rough, and I mean ROUGH, idling and heavy soot from the exhaust. The EGR was coated with carbon soot, and can be cleaned with a small brush like you would use to clean a small beard trimmer. HOWEVER, it turned out to be the spider fuel injection and it needed to be replaced. But the EGR still needed to be cleaned. Those bastards are expensive!
