I am hoping this is a simple common problem.
When I step on the brake pedal while stopped the idle goes up about 300 rpm's. This started after I had a shop work on the clutch linkage. Before I took it to them the situation was opposite. When I would step on the brake while stopped the idle would go down 300 rpm's. The shop did tell me they turned the air fuel screws to make it run better. It does run better, albeit a little warmer now. Is this a brake booster problem?
