Try replacing the fuel injector o-rings, I understand this is a common problem.
Quote from article - Top Ten Mods for 16V cars, by Alex Ranarivelo. "If you haven't ever replaced the injector o-rings on your 16V, you MUST do it. You are lossing power and gas mileage. Make sure to replace them with VITON o-rings, not the standard rubber ones (the 90-92 cars came from the factory with VITON o-rings and are good for 80-100k). You would not believe the difference these $1 little things make in your engine's performance. Remember vacuum leaks are BAD, they throw off your fuel mixture." Also in another article he says there were recalls on computer wiring harnesses and if you have a "idle/bucking problem" make sure these recall have been done. Secondly he says that corrosion at the electrical connections around the engine are to blame for a majority of these problems.
