You can have a broken tab and not even know it. I checked mine not too long ago and it was broken (~105K miles). I didn't have any odd/strange noises prior to checking.

Thanks for your sharing. That's good information for me. I'll check it for sure

Been driving the car putting some miles on it. I changed the oil and filter along with the ultrasonic cleaning of the vanos valve body and regulator.

The afr at idle is in the high 11 and mid 12s and I see 13s at times as well at idle. Car runs well and the odd time I see mid 10s but climbs up to 11.5 or more.

This is the best I have seen.

High boost is 10.00

Battery harness , crank sensor and intake cam sensor will be here this week. I'll install them try it then send my logs down to Hpf. From there I'll see where things r at. I'll also check the vanos oil pump tabs.

No symptoms at all. With the recent horror stories on the forum I decided to change the cam gear bolts and fully inspect the vanos exhaust hub. Turns out one of the tabs was broken My engine is stock so I don't have an air/fuel gauge or a bazillion engine codes

So I went to check my spare sensors today and looks like I was given the wrong spec MAP sensor...I have a 50PSI one and the spare was a 75PSI one...mabe you were given the wrong sensor back when you swapped them.

I had checked and it was the correct one .but The one I did get was faulty and I had it replaced.

Any ideas why my afr would be better with the ac on?

Good one. Now what would more load cause a leaner afr at idle?

Been driving the car all week. Lots of miles. Afr ranges at idle from 11 cold to 12s to mid 13s warm. Best it's ran so far and no fuel smell. I'll be heading back to my tools so I can make a few more checks and changes. Then off long haul with the car

Pulled a plug just to see what's going up after several days of driving. ( theres some old carbon residue that hasn't been burned off yet from when it was running rich) looks great.
