Meaning with some vehicles it has to be driven 30mph for 5 minutes, then WOT on the freeway ramp, then 70mph for 15, then 5 mph for 25 minutes, with at least 80% load to test short/long fuel trim when EGR valve is opened then.....so...anyways you get the point.
The computer wants all possible real world driving being accomplished
But for the weekend-trips-to-the-store granny, this would never happen. |
Yup, battery died on my Mazda. It was due for annual. Yanked the battery out of the Benz and ran it up to the shop.
Guy tells me I need to drive 60 miles before they can smog it so the computer is calibrated.
