Haynes manual says... " Do not attempt to clean the interior of the throttle body. The throttle body is designed to resist sludge accumulation and cleaning may impair the performance of the engine"
well my throttle body has sludge in it, on the engine side of the plate, do I try and clean it out? Wheres the dirt come from? the air filter is pretty clean, the MAF appears to be pretty clean, does it come from the inside, I have no oil loss, if any its a pretty small amount.
