Mass air flow readings.

Post by maggarjt » Mon Oct 05, 2020 1:30 pm

So I bought a 2005 vibe and have done all the preventative maintenance on it I could. The lady who owned it did very little. I recently got a scanner and noticed the MAF readings at idle (warmed up) is averaging 1.65 increasing to 18 or 20 at throttle of approximately 2600. Does anyone else know what their MAF reads? That seems low.

again, these small japanese engines are like a crying baby. When the baby cries, it normally is one of two things: it's hungry or it just pooped. Let's put the poop aside for the moment and begin with the hungry. Do you have fresh Denso plugs and Denso ignition coils in the car?

Please post the list of all of the codes the vehicle is throwing. This will be able to help us paint the picture of what is going on, and what may need to be done to feed the baby. Just gotta have the right formula sometimes.
