too much fuel

Post by 78f250 »

i have a 78 ford f250 its running a ms 2 i cant seem to get the low end bog out of it and the other day it back fired throught the intake and now it dumps so much fuel that it will hardly run. could the map sensor have been taken out by the back fire. Any ideas?

It certainly could happen. What does MAP read now as opposed to before the backfire?

Log and msq would help.
