1999 turbo saab 9-3

Well, a non functional TPS will certainly give you all sorts of problems.

As far as the allen key goes, it depends on what kind of access you have to the head of that bolt. A couple of strikes with a hammer to loosen the broken end and something to fish it out is all I can think of at the moment...perhaps a piece of coat hanger with a dab of super glue would be enough to fish it out...just make sure you don't end up gluing the broken piece in the bolt

I get no reading at all.

The other problem I'm having is replacing the alternator. The alternator is attached with 2 long hex key bolts. On the first bolt, I broke off the round end of my allen key. I've since got a set of allen sockets, but am having a problem getting the end of the allen key out of the hole. Any suggestions?

This MAY sound stupid, however, get a shop vac with the small snorkel and hold it by the broken bolt head . The tap on the alternator frame right next to it. If it gets free the vacuum will suck it up.
Get a new TPS. The ECU has a hard time without it's input.
