Hi fellow JK owners, after reading thread
http://www.ausjeepoffroad.com/forum/...ad.php?t=67074
and thinking it was for my JK for some reason i proceeded to clean the part called the Boost Control Sensor. It was a 5min job after finding where the part was as the other instructions on the above thread were for a KJ.
while standing on front of jeep, if possible
located place of sensor and use product such as cleaner on right
remove electrical connection first where yellow circle is, then finally remove hex bolt using 5mm alan key. Then wiggle sensor and remove. Spray with cleaner, mentioned above, till all black gunk has disappeared then reinstall. Piece of cake.
