Are you looking at the instrument cluster display, please? (The orange line of text just below the speedometer)?
You use the instrument cluster display, not the Nav screen, for these tests.
Print the first post in this thread, and the post linked from it, and follow those instructions step by step, and it will work.
It seems you are looking at the correct display, but you havenŽt switched to
the hidden diagnostic mode yet. You need to do that first. It is described in complete detail in the posts mentioned. Print those, and give it a try. If it still does not work, let me know, and IŽll figure something out.
i got 137 in second gear first run..second run i got 139 is that good or my maf is bad...the temp here around 33 c..
My raw numbers displayed were 106-107 with old MAFs. After replacing them, I saw 108 - 112.5 and figured that the variation was the DME adjusting. I might just drive over the hill Monday to Sacramento (25 ft elev.) and check my numbers. It sounds like our numbers were indeed similar before I replaced the MAFs. Have you replaced yours recently?
Eric & Mark,
We donŽt have very much data from high altitude, so yours is especially appreciated. If you have some environmental data too (temp, barometric pressure, altitude, humidity) it makes the data even more useful.
BTW, I can imagine the dialogue going on:
Husband to Spouse:
Darling, I need to drive an errand. Just to check if the car gets stronger with
lower altitude, so IŽll drive to the Pacific and back, just to check if the fuel flow numbers gett any better. IŽll be collecting Data, all for Science, you know. See you in a couple of days, hon!
