I have a 88 gxl that has been having too many problems to count and I replaced the afm, vacuum lines, injectors, and fuel pump. I finally got the car to run okay, it was cutting out under 3k. I replaced the rubber hose that got eaten by ethanol (e10) and i had the tps unplugged and it started rough but better with it unplugged. I can't get it to run again.
