This started when I put my 7 bolt head back on the 6 bolt block. Car is a 99gst. Black top cas. Im on speed density and as you can see the car idles fine if i don't touch the gas. When the touch the gas pedal it goes rich and then super lean. It died a few times doing this. The car also drives fine during vacuum but it stuters bad and vibrates trying to build boost. I ordered a new fpr and a new fuel pump. Anyone have any insight on this issue?
