Ok here goes. This is the first (and last) Audi I've owned. It's a 97 1.8t. I bought it from a friend of mine who knew nothing about nothing when it came to doing work on cars. It was mixing. So I took it and replaced the head gasket, timing belt, and water pump. While I was at it I replaced the plugs, coil packs, and air filter. Then thecar drove ok except for under a load (when I pushed the accelerator more than half way down) it would buck and jump and act crazy. I took the MAF off to clean it. When I put it back together it wouldn't start at all. So I've replaced the MAF with a new one, and now it will start, but it won't idle. I have to continually pump the accelerator for it to run, and now it smokes around the turbo. I can rev it up a little and when I take my foot off it makes a strange noise like I have a blow off valve. I don't. The CEL doesn't come on. I dont have a code reader so I don't know what it's throwing. I'm moving back to America in the next month (I'm a soldier stationed in Germany) and I just shipped my tools. I have access to a place with tools, but need to figure out what's going on before taking it there and wasting more time on this POS. I know I've thrown a lot in here, but I like to be thorough. Thanks to anyone who can help.

 

It could be a boost leak. That happened to my friends GSX, it would idle like ****.
