Default Re: Horrible MPG drop..

MAF is clean, always is I make sure of it. Where should I possible check for a vacuum leak? I did not get a look at the measured fuel ratio the OBD2 scanner at work sucks apparently, and I no longer have access to a Snap-On OBD.. I'm sure I can ask a few shops I know.. And yea... No F'ing codes...

Edit. And on those readings, it was .238, i had it written down in my truck but was to lazy to go out and look. Lolll

I agree with Tim, on the O2 volts ,looks ok....and it does suck not having access to a good scanner.... if you do happen to get your hands one again, check to see if your in close loop after it's warmed up, although it should have threw a code if it had stayed in open loop too long....Also check intake temp to see if it's correct, should be within a couple degrees of actual outside temp. Check coolant temp too, If the ECM see's a coolant and air temp that's really low it may command a longer than normal injector pulse width...
Not unlike driving around with the choke on...

If you had an actual vacuum lt would have thrown a code..

Simplicity is the ultimate sophistication.

Torque it down till it breaks off, then back it off 1/4 turn.
