All assembled with vanos plate sitting on top. Now put back reversed way of torquing the five 5mm bolts to 10Nm in multiple steps. The thin plate can be slipped on once u get the main value body as selinoid is repositioned underneath top vanos unit.

Start up after plugging in vanos cable. Check for leaks. Reset codes

Ok started it up. The afr was 12 to 13 right away. Before the change the afr started at 14.7 and worked its way down to 11s. The car had way more power from 2 to 4 grad rpm. It was a whole new car. Way more power uptop as well and noticiby revved much faster.
Before the value body change it was like it didn't want to rev high yet pulled hard Tells me the cams r now working properly or at least better than they were. The afr at high boost is still 10.5 or 10.9. Which is still troubleing. I'm glad I'm on the right track.

Are you absolutely there are no boost leaks? It def sounds like its sucking air in through a leak causing a rich condition.

You can make a home made boost leak tester for about 30 bucks with home depot materials

This is what you want! Anything >11.5 would be considered bad. You want it rich in boost.

New development. I was refilling the meth tank and ran the test / purge jumper. The car now runs afr at idle 10.5 jumps around to 12s. Messed with the jumper box and harness going into the dme and seems to make some difference when it went in the high tens again. I even seen it at 10 as well So I think I have some cable issues as well somthing else. Man this can be disheartening

I'm running 20 inches of vacume and 22 to 24 when hot. I'm don't think I have a bost
Leak. My erratic idle is what's got me Concerned. I'm also seeing high idle rpm above 1100 and takes a while for it to settle down even when it's warm or hot. ???

I let the car sit and I resorted the wiring harness and put the top back on loosely. Afr back to 12 at idle.

I ll have to drive a bit to see how it holds up. It could also be the used vanos valve body being flaky.

Car goes into 10 at idle and smells bad. Cleaned the ICV and put back the old vanos value body and the car does the same. ???

It seems that 10 at idle is bad and it's sitting that way a lot of the time. Once and a while it is in the 11s

High idle, rich conditions etc are all signs of boost leaks, test it with a home made boost tester to make sure 100% there are no leaks, or take it to a performance shop and they can test it there.

With that said i love how hpf just sits back and watches you suffer while you pour countless of hours and dollars into the car, after they ok'd it and said it was fine to leave.
