The fuel injectors are batch-fired, not sequential, so yes, they will all spray at the same time.
If you swapped distributors and no change, then you've covered that, and the coils hardly ever go. I'd swap the primary wire just for fun.
I chased a rough idle for a month only to find out that I had my distributor vacuum advance hose plugged into the wrong port on the throttle body. The effect was that I was getting massive advance at idle due to too strong of a vacuum pull on the vac canister of the distributor. So vacuum hose routing is just as important as having the hoses intact.
So this is a '90 SPG? Does it still have the EGR system hooked up?
