Hey ya'll! New to the forum, excited to be here. Bought my '91 XR2 about 6 months ago in Seattle for a move down to LA. A small, sporty, red convertible with boost seemed like a good car for the Los Angeles area :-)
And although it was boosting great the first couple months I've owned it, I noticed a significant drop off on my commute home recently. The boost gauge will still move - but only a little bit - it doesn't ever make it much past 5. Also, the boost used to kick in with a small push of the gas pedal. Now is only seems to engage when I have my foot to the floor and high RPMs. Basically, it feels like the boost is about 20% of what it was when I bought the car. No smoke, no noises, just a smaller amount of boost.
I've owned SAABs in the past, and it was often the case that a simple vacuum hose popped off and killed the boost. It was an easy fix to re-secure it and things were back to boosty goodness. Was hoping I might have the same luck with the XR2, but neither I nor a mechanic (who only took a cursory look) saw anything out of the ordinary.
Has anyone had this issue in the past? Are there any "known" things I should investigate?
Thanks in advance for any thoughts!
