I drove the Super Volvo today. Floored it. lots of hesitation. wimpy..down shifted etc.. The Egr vac PSI goes to zero but needle bounces around between 0 and 2. That makes me think I'm loading inert gas to the cyl when I accelerate.
Next test was to disable the vacuum to Egr. The engine accelerated smooth , no missing. The car is still slow.. but it accelerates smoother.. interesting.. My Egr valve maybe acting funny. I almost want to have the emissions checked to see if I am running rich.
