I'm registered to have my car in a show in one week. I bring my car to the upholstery shop to have the door panels done and I go over my car w/ the owner of the shop in case he needs to move it. He calls me a couple days later to tell me my car is not acting right. It's a 65 Riviera and has a ride tech big red max 4 way system with shockwaves in the front and cool ride shocks in the rear. When I turn the compressors on and try to raise the front, the driver's side front shockwave instantly dumps air as fast as it gets it causing it to bounce a little. Also the rear p***enger side will not dump any air. If anybody can point me in the right direction to trouble shoot this, I would greatly appreciate it. It's never given me any problems until this and I've had it for about 10 years. Thanks, Dave
