I recently changed the timing belt on my 91 Audi V8 with a 4.2 from a 93.
The first time, i got the timing one tooth off, and it ran very poorly, if at all.
Anyway, i purchased all the needed tools, the cam locks and everything, and set it correctly this time.
However, it wont start.
Last week i purchased a Ross Tech diagnostics unit to hook up to my laptop.
Here are the five fault codes it gave me for the engine.

I have ordered a camshaft positions sensor from my mechanic, and am waiting for it to come in.
I have also read that the Throttle position switch may need to be cleaned, i will post the link later.
Any ideas what to do?
It turns over and everything, and sometimes it almost starts, but doesn't. I can post a video tonight or tomorrow.
