AFR will jump around a lot depening on what the conditions are. Not sure what proper is with the EB trucks, but I know on LS engines it's ok for it to be around 14 or so at idle and in the mid 12's or so WOT.

Your ecu is always adjusting the fuel trim. Even at wide open throttle. It should be bouncing.

"Your ecu is always adjusting the fuel trim."

Timing too!

Hi.

Pleas go ask a Mod to merge yer two exact same topic threads.

==> https://www.f150forum.com/f38/afr-246095/

That way all the info will be in One Place.

See what a mess Cross-Posting makes? Not cool and against the rules.

Thanks
