My car is pulling 10hg of vacuum at idle but will idle up sometimes and run right at 18-20hg. Whenever the problem is happening the car will be super sluggish until it goes into boost and them it runs fine as long as it is in boost. When it goes into boost the wideband shows 11:1 but when the car is doing the weird stuff it shows between 18-21.9:1. I have checked for vac leaks and found none. I cannot figure out what is going on with it. Has this happened to anyone else? I didn't lots of searches but could find nothing of the sort. -Tim
