Hi everyone, Im new to this and not sure if im on the right page or not but i have a v5 wrx sti and when first started or driven it will drive fine but once its at full working temperature if idling and when it comes to a stop the rpm drops to idle it will cut out it smells very rich i have checked the voltage on the air maf sensor which was 3.5 volts idle and decreased as the rpm was increased i have always known for the voltage to sit at around 1.3 volts and increase voltage as rpm increases with other models not sure with this model impreza is there any other check or sensors that could cause this fault.
if anybody could help, would be appricated.
cheers
