have you pulled codes?

Have you pulled codes from the engine? Is it easy with your '94? I know it is easy with my '91.
How's your exhaust system? Is it intact?
My '91 9000s was stalling, I looked at obvious stuff, but then finally pulled codes. Mixture was off, the computer said it was too lean. I had sort of a eureka moment and realized I needed to replace my exhaust header.
Now, in my case, the previous owner had taken the car to a shop and they had welded every segment of the exhaust together, so I really needed a sawzall and a header, cat converter, front muffler, inter pipe, rear muffler, and tailpipe, but hopefully you'll need less if this is the case.
The symptom for me was loud exhaust and engine stalling. Exhaust was leaking out of the flex-tube portion of the header and the oxygen sensor was reporting erroneous information to the computer, and choking the engine. If you just want to keep running and don't mind a slightly racing engine, try opening up your throttle a little?
Anyway, just passing along what my stalling problem was. Certainly it got fixed right up with an intact header.
