i just had the same problem this past sunday. car just died. had to floor it to fire up. took air cleaner off, driving down the road it started screwing up, saw gas mist on windshield & gas pouring from the vents. bowels were clean. i'm changing my magna fuel reg.it's 9 yrs old. didn't take it off yet. i'll let u know what i find. prosystem told me to isolate the reg with rubber to keep vibration down.
