I ran very low on fuel a couple weeks ago, and since then my GN runs rough. I changed out my fuel pump and fuel filter, but it still doesn't drive any better.
It will run good for the first 10 minutes when I leave in the morning, but after that when I accelerate it hesitates alot. It sounds like I am running out of fuel.
All hoses are tight, and I tried knocking on my LS1 mass airflow sensor to see if that would cause the same choking, but it idled fine.
What's wrong w/my Buick?
Could it still be my mass airflow sensor?
