I have to work it for some time, seems that it wont turn unless its in the right place, which is fustrating. any ideas?
** also when i do start it, it seems to idle low, and shake? but after putting it in Drive and running for awhile, seems to stop shaking?
(Latest maintenance) Replaced all 6 fuel injectors

I had the same problem on my '91 sedan, something in the ignition switch was broken, I ended up having to replace the whole steering column becuase it was easier than taking it apart.
As for your rough idle, there is a specific idle-relearn procedure for it.
Idle Relearn Procedure
1. Reset ECM by pulling ECM fuse (15A Blue Fuse) for a few seconds.
2. With A/C turned off, start car and immediately put it in Drive with your foot on the brake.
3. If the car does not start initially, keep trying WITHOUT putting your foot on the accelerator.
4. Let the car idle in gear for at least 5 and no more than 7 minutes.
5. Shut off the car for 10 seconds.
6. Start engine, place in drive and let idle for 5 minutes.
7. Shut off engine.
8. Idle is learned.
