Christian, I will concur with Jwit. If you will take off the front bull horn on the intake manifold, you will see the butterflies in the throttle body. Clean the grung out and final clean with Berrymans B12 spray. They have to close all the way. It only takes about 30 minutes and I clean mine out about every two or three years. Even better if you are ok with mechanic work. Take the throttle body out to really clean it good, then relubricate and reinstall.
