the car is a 1984 gti rabbit
I just removed the throttle body rubber boot and sprayed the throttle blades with carb cleaner, I tok a toothbruch to them and got them clean
I also removed the boot from the air sensor plate (above the air filter) and claned the plate and hte surrounding surface. I took a magent to the center bolt on the plate and lifted it up and cleaned the edges and mating surfaces.
now my idle is about 200 rpm higher.
is my car now running richer or leaner?
