I sort of hoped this would go away but he still hasn't found a resolution. Thanks for the replies. We did change the temp sensor and no change in performance. I've found lots of bits of info but is there a thread or writeup that covers where to check pressures? I saw a link at one point to a cheap harbor freight gauge but now I can't find it again. Anyone buy one and have a part#? We found a comment in the service manual that describes the condition of the car to a T. The recommendation is to raise the pressure. I believe it was to raiser the lower chamber .5 bar higher but I could be way off on that. Don't have the numbers in front of me.
