Shaun told me about that once when I was looking into a Walbro 255lph pump when I thought mine was going bad. He said that I could go pick up a stock pump for a Buick GN I'm pretty sure it was.

255 was an upgraded pump for the GN's. GS340 I think it was.

Tape a fuel pressure gauge to the windshield and drive the car to see what the fuel pressure does while duplicating the issue.

Gee a carb wouldn't have fixed it. And Timing was dead nuts (spout out) Not an idiot! Fuel pressure is good. It was the coil, must be weak under load....... new coil no more problems. runs grrrreat!! (tony the tiger) But thanks for all the feedback..... so much for internet diag...... right John!! LOL
