Subject: stuck wastegate


I have a 1995 9000CS with 145,000 miles on it. I've been having an acceleration problem with it. It has the 2.3L LPT engine, rated at 170 hp. When I push the accelerator farther down than about halfway, it bucks violently. My mechanic has diagnosed it as a wastegate that gets stuck closed. He says the turbo pressure builds up and supplies too much boost. Then the computer notices it and cuts the fuel supply. I wouldn't mind except that it causes violent lurching, and it's quite unpleasant. He said he squirted in lots of anti-seize and worked it back and forth a lot. (I have no idea how hard it is to reach.) It was fine for two or three days, and then the problem came back. I have to drive gently in order to prevent the problem. He says that at this point, my choices are 1. live with it, 2. he can do the same thing, and it's likely to recur again, or 3. pay $800 or $900 and get an entirely new turbo unit in. Are there any other possibilities? I don't know how these things are constructed, but it sure would be nice to replace the wastegate and leave the rest of the turbo. I don't think I want to live with this problem, because I want to sell the car soon, and I don't want to sell the car with such an obvious defect. Thanks. Tom Reingold Noo Joizy
