Okay then... here's the situation in as complete yet concise as possible. FYI, I've had three 900s and worked on them, but this is my first 9k so I need a bit of help and all suggestions are appreciated.

TCS poppped up on my 93 9k cse Turbo Automatic the other day. Checked the trionic code and it came back for the throttle positioning sensor.

I had recently replaced all my vacuum hoses, so I checked to make sure they were all still connected. Took it for a short drive and about 5 minutes in TCS popped up again, and it wouldn't even go into limp home mode.

I had to manually adjust the throttle cable so it would even go into LHM. Until I did, it was idling along somewhat roughly at about 200 rpm. When I went under the hood and jiggled the wire it moved to limp home mode and I was able to make it home.

I ended up taking off the hose from the intercooler and checking out the throttle. Looked pretty clean, but the butterfly was hard to move. Might I need to lubricate the cable? the throttle?

Now the interesting thing, while I was tinkering, I noticed a hissing sound. It was coming from the line that goes from the PCV check valve into the intake manifold. I disconnected it, restarted the engine and voila... back to normal!

I reconnected the hose the next day and after about five minutes, here comes TCS again.

Now for my immediate plans, I plan on taking this to the dealer to get the codes read. I called the dealer and an indy and they were both talking about it taking an hour of time to hook it up and diagnose the codes. Do I want them to spend the hour, or just hook up the ISAT/Tech II and spit out the codes?

Second my indy told me that he just had to finish replacing both the Electronic Throttle and the ECU which the old throttle fried so that it couldn't be calibrated. Sound like it could be true?

Any ideas?
