[bass87gn]

Im new at all this,heres my scanmaster numbers

Af- 08
L8- 50-55 numbers are going up and down?????
Bat- 13.5
Int- 128
Bl- 115
Mph- 0
clt- 173
ats- 75
r- 800-850
tps- .44-.46
Iac- 12-14

Why would the l8 numbers go up and down? and the tps is going from .44- .46
Any advice would be greatly appreciated

You probably have a bad MAF. The airflow reading is high for idle, which will drive the BLM low. LV8 is based on the airflow reading.
