Post subject:  Limp in & ORM related?
Lately with my new commute to work - lots of stop and go - the Great Mysterious Limp In problem was happening almost daily for 3 weeks.

When I started having the TC slip problem (noted in another post) I plugged the MAF back in in preparation to take it to the stealership. I drove it for about a week and a half like that and several things happened:
1. What's with all this turbo lag!? :roll: How spoiled we are now!
2. Mileage went down a bit.
3. Blew black smoke on hard acceleration for a couple days. Guess the EGR is cleaner now.
4. Sets a P0105 MAF Performance Fault occasionally at warm idle - don't care it will be gone again soon.

and finally

5. It went the whole time without a single limp in event.

So is this just coincidence? Do people not running ORM get limp in? What about with the SEGR? (No my Rev 1.0 kit still isn't installed.)

Sounds like your vacuum system is problematic, from turbo-lag and black smoke complaint and limping - have'em checkit out

I wasn't worried about 1-4 after running the ORM for 40,000 miles over the last 12 months.
The lag was what it had before. The smoke went away afer a couple days, no doubt gunk in the reactivated EGR, I shudder thinking about all that garbage in my engine. Just another possible theory/a little more information about the persistent limp in problem many of us seem to face.

I can't exactly tell the stealership "I usually run it with the MAF disconnected but when I do it sometimes has no power when accelerating from a stop." :lol:

They're replacing the valve body in the trans under warranty, hopefully that fixes the cold start problem...
