Please HELP!!!

I just recently did 60k maitenence on my SHO. Now I am having problems. I was having missing and killing problems that come off and on. I couldn't figure it out so I brought it to a shop and they said it was the CPS so I paid $400 to fix it. Well it didn't fix it. So I ran the codes myself and the only thing I got was the Intake Air Sensor. And it seemed to be temp related (doesn't act up when cold outside. So I changed that.... still didn't fix it. Just ran the codes again now i get a 126 and 211. Please help I am sick of spending money and not fixing the problem!

Oh yeah I also got a 214. Does that mean it is my Cam Sensor?

If you are getting both the 211 and 214, I would look at the DIS module and its ground path. Are the two, 12mm bolts tightened on the crossover tube? Is the groun strap attached to the rear passenger side upper intake bracket bolt? Are the DIS connectors tightly attached.

I checked the crossover tube bolt and one was loose. Would just one of the two bolts loose cause that? I haven't drove it to see if it works, but it's worth a try.

Thank you very much. The crossover bolts where loose and that fixed it. So much for spending $400 at the shop. Just two damn bolts!!
