what is does it mean when you start to "run rich" after a header install? and what do you do to stop from running rich?

Default Re: running rich

it means that too much fuel is in the mixture.
Its measured as a Air/Fuel Ratio
To lean it out is too go more air less fuel.

a MAF-T works

Beware, not all who think they're running rich really are. They go by smell and O2 readings. Not very scientific and very often misleading. A wideband O2 sensor is the way to go.

Default Re: running rich

he's right ya know
best way to find out is find a local dyno with a wideband A/F meter
i dynoed mine last week for the first time, and got to see my awful mid 11's on the wideband <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Yup, you just never know 'till you dyno with a wideband. After headers my O2 readings were .900-.930mv. You'd think that was on the rich side, right? Well, I had it checked out at MTI and it was 13.3:1. Definitely NOT rich!

My car is way lean! I dyno'd with stock ported MAF ends and on the sheet, the AFR hits 16:1 then drops to 14.1:1 till red line. I put in a post, but few have responded. Some said to use MAFT. Any opinions?
Thanks.

If you have an uported MAF I'd try that. If not, check for vacume leaks. If none, turn the MAF backwards. That will richen it up *some*. I don't know if it will be enough though.

But yeah, a MAFT will fix your problem.
