91 talon no power

[raybeez63]

I have a 91 talon AWD turbo automatic. When I accelerate from a dead stop the car revs up but doesnt move really fast. Maybe 15 mph. It takes about 20-30 seconds of driving to actually get up to speed. This will eventually get me killed as I pull out onto a freeway.
This happens just about every time, and I'm not talkin about burning out, but just pulling out at a normal rate. The car feels like I have a giant parachute hooked behind the car. The car will not get out of it's own way.
So far the fuel pump and air filter has been changed, plugs plug wires are ok, tranny fluid has been changed and car was taken for a test ride by two different tranny shops. They both think that there's nothing wrong with the trans.
My mechanic is baffled. Hooking the car up to the computer reader shows nothing.
Defiant (dsm member) passed onto me that it might be a driveline problem. Possibly failed viscous coupling.
Any and all help with this mystery will be greatly appreciated.

Replaced bad fuel pump, and (the biggie) a faulty wire connection for the ignition module
control switch. Car now pulls out normally, but still is not up to what I would call par.

This weekend I'm getting the exhaust checked... going to gut the cat and see if that improves performance.

Hey i have a 1990 TSi AWD and awhile back my car had no power to it like it would take half a day to get up to 30mph. i took it to a dealer and they said the actuator arm on th turbo was frozen shut. :thumbdown they are dumb and wrong. the turbo was fine it only has 60k on the whole car. i took it to a small competant shop down the street and he said the injectors were bad. he was right. i replaced those car ran 99% better and then later that night it started to act up again. i replaced the Fuel pressure regulator and fuel filter car ran 100% better and stayed that way until my tranny took a shit right on my face on the highway but thats besides the point. try the injectors, fuel filter, and regulator. it worked for me
