Volvo 940 Throttle Body Service Tutorial
940 throttle body service – Very clear write-up with good pictures
My efforts to improve the durability and drivability of this 16 year old car continue. Today I cleaned the throttle body. As you all know, modern cars route blowby exhaust gases back into the intake in order to burn them. This causes coking in the throttle body which must be periodically cleaned. This is an easy service requiring few tools and is suitable for a beginner.
