Another thread had morphed into touching on this subject but I thought I'd post it directly as it sounds like a few folks have had great success as a result of cleaning the throttle body. So, for a guy like myself, can anyone explain how to do this on a FZJ? Pics? thanks, Jason Also- Has anyone considered that the high rpm start up/idle could be the root cause of the notorious 80 series driveline clunk? i.e. the Higher the RPM's when it is put into gear the more stress is put on the driveline, thereby creating more play in the driveline components, eventually leading to the clunk being present even at normal idle? By all means, slap me if it sounds impossible. (ducking now).
