Hey guys. I need some help. I have a 2000. Gmc sonoma with a 4.3l in her
Resintly i went to go to work. A started my truck up and it back fired on me
The engine stalled out, and when i went to start it again
The engine revs started pulsating, it would rev to 2000 and start to
Sound like its going to stall out and then it would go back to 2000. It would keep doing
That in till i would shut the truck off. A buddy of mine told me to replace the
MAP sencer and also the evap purge on the intake. I replaced both and
The problem still is there. Now heres the werid thing i unpluged the
Mass air flow sencer and the revs stayed at 1500 to 2000. Has any body had this problem befor and know what to do?
I cant figur this out...
Btw sorry about my gammer and spelling im typing this on my phone
