David's Farm Help!!!!! 1993 Chevy Astro Van 4.3L V6
Ok David here is the video.
The engine idles alright a little rough but when I give it gas it acts
normal revs fine and all, but when I put inito gear it starts running rough
then when I push the gas it barely moves then when I give it more gas while
in gear I starts backfiring out the top of the throttle body and you can
see flames in this video it acually dies at the same time it backfires.
So are I have gotten gas out of the car let it sit in a jar for a little
bit to make sure no water was present there was no water present in the
I replaced the fuel filter
I have hooked a timing light to each spark plug wire to ensure they were
all sparking and they were
I tested all the fuses no blown fuses
I unhoooked the MAP sensor to see if there would be any difference in how
the engine ran. It ran pretty much the same, but backfiring was not as
present with MAP sensor unhooked.
Unhoooked the battery for about 30 minutes to clear computer codes and
reset computer. That had no effect on how it ran.
I jumpered the computer to recieve codes. The codes listed here:
33 MAP sensor
34 Vacuum sensor or MAP Sensor
43 Electronic spark control unit
I believe that codes 33 & 34 were set when I unplugged the MAP Sensor
Anymore questions please feel free to ask!!!!!
Oh yeah it's got over 300,000 miles on it
Thank you in advance

This new to the scene Chevy AWD Astro Van was a fan favorite and didn't
disappoint the crowd. But unfortunately in the end, it wound up breaking a
hub I think...
