MAF CEL and boost gauge light fixed
by Matt on January 10, 2010
Swapped in Brad’s Bosch MAF. It finally fixed my CEL that I have been trying to diagnose for 2 months!
I also rewired the boost gauge to make the light work. For the first time in 2.5 years of ownership the boost gauge can be seen at night
