Engine light is on. Code reads maf voltage. Changed out maf. No difference. Found vacuum leak. Fixed that. No change. Read it could be writing for the maf. Anyone have this issue before or can point me in the right direction? Trying to get this running right before monday...
 
what is the exact code?
