This is on CA 91 octane, 74 degrees out, slightly humid so-cal night. Log is block 3. I know I clicked it off early (traffic). Extrapolated fats is 7.89, I know something ain't right.

Anyone care to point me in the right direction on where to look next. I know that MAF seems very low compared to what's in the archives. Not sure about the timing either. Any common symptoms for low MAF readings? FWIW I am missing the O-Ring between the airbox and the accordian hose to the MAF sensor. Could that be the cause?

Thanks in advance,

Elevation? Sure would be nice to have that o-ring.

Santorin_OX

I'll be putting it back in as soon as I can but I don't think that would be a cause for low readings.

PSmalls::AnalRetentiveNumbNut

boost leak maybe?

Santorin_OX

i was thinking that's a possibility, guess i'd better pressure test and log 115. Timing look ok?

PSmalls::AnalRetentiveNumbNut

I think you mean 115. Sorry, been too long since I've seen stock timing but think it's OK.

Santorin_OX

I did, fixed the typo. Thanks for your help.
