A4 Burning Rich Overheating Turbo
 

We have a 1997 A4 1.8T, Quattro. The turbo and cat. converter were glowing they were so hot. We thought the converter was clogged so we gutted the converter and put a new turbo on. Since then the turbo is still getting hot. The mfg of the turbo said it sounded like it was running rich on fuel and it is. Code read that it needed MAF so I replaced that. It is better but still running rich and turbo is hot. It has started "bucking" at higher RPM. A new code came on today stating "Evaporative Emission Purge Flow". Any advice would be greatly appreciated.

Anybody have any suggestions? What's the reading from the vent valve this evap code is being registered?

Unfortunately, I should have done some homework before buying this Audi. It died on me today. I got it home but its always nice to have the car die on you the second day you own and it and only putting roughly 65miles on it.

Any help would be appreciated.
Thanks
