Mass air flow sensor (G70): signal too low
P0102-35-00
Readiness: 0010 0101

 

look at your #30-#36 fuses before you replace anything. one of those is directly related to the motor's sensors. i cannot remember which, but it is probably #34.

 

Ok i will check those fuses and report back
Thank you

 

Could be an odd hose thats disconnected. I had that code twice, once for a SAI pipe that came loose, and once for a loose TIP

 

I checked the fuses and theres fine
Wheres is the sai and the tip?

 

I was lookin around my engine and noticed a old brittle and cracked line, so i replaced it and i got 20 hg now
(i was at 18 to 19) i was thinking about replacing the line that runs from the front of the engine down to wat i believe is the dv? The line has like a braided cover and it looke oem. Couldnt hurt right

 

You have a lot of years on that engine, i would replace all the vacuum lines, the suction jet pump, and all three vacuum check valves.

 

Ive been replacing the vac lines as i notice them
I replaced the check valves, one was completely cracked with a whole the size of a dime on the bottom, wheres the jet pump and is there a way to see if its bad?

First four listings on that page, it sits right next to one of those check valves on the back of the engine by the manifold. When they go bad there is usually a huge vacuum leak and the engine barely runs, they just break apart with age.

 

is this the Y connection right by the oem airbox where one side leads to a check valve?
