My internet research suggests this is a vacuum problem. I have seen it suggested on a few sites... i.e. Here
Also some jerk was nice enough to run a red light and bang up my front right corner 2 years ago. Repairs were made but I believe there is a vacuum box somewhere behind that front passenger fender. The problems are new but maybe the damage to that area caused something to work loose.
What do you pros think? Does anyone have a vacuum diagram so I can try to chase down a possible leak? Thanks in advance.
