Ok, so the center runner arm and mechanism were broken, and I put a new Intake in my 06 SLK 280 (R171). New gaskets, head bolts and vacumn lines/hoses as necessary. After driving 40 or 50 miles, I get a barage of 6 DTCs: P0170, P2015, P0173, and another (second set) of P2015, P0170, P0173. (???) Car idles funny, but observation of the intake verifies that all 3 runners working normally. So I do a reset, and in 30 or 50 or maybe even 100 miles, Boom...Check Enginge, with the same 6. I've looked and looked, double-checked every connection I can see, but same thing over and over. Any similar experiences? Ideas? Suggestions?
