I have low vacuum pressure, it is reading about 15in hg and I am getting terrible mileage. I replaced all the vacuum lines. I have a scanmaster and the readings are
Knock 726 ret. 0.0
Maf 5.0
LV8 38
Volts 13.4
Int 128
BLM 127
Speed 0
Coolant 178
Air 119
Rpm 725
TPS .42
IAC 16
O2 55 and steady
Open loop
No codes.
Wondering what I can check, not sure if it could be internal. The scanmaster seems fine, but Power is down and mileage is terrible.
Thanks for any comments.
