checkin Cats quick?
Getting my ws6 ready for summer, tune up so far gone good, just need to check all eng sensors now and I was wondering if there was a way to check if your cat converters are clogged (or getting there) without taking the o2 sensors out?
took her out last night and it bogs when i have it 70% throttle or more
could still be sensors that i havent checked, but isnt there some vaccum way of exhaust restriction??
thanks

Have you checked fuel pressure? I'd do so not just at idle but at WOT when the power loss is occurring. This is a more likely cause based on your description IMO.

Looks like you have already found your problem then, it should be closer to 60psi. Also, it *should* remain consistent at WOT, but often times a weak pump will still show good numbers at idle but drop way off under load. If you're already at 44psi at idle, and you trust the gauge, then you needn't look further for your power loss issues.

You might want to replace the fuel filter first, just to make sure that it isn't a clog causing the issue. Also, not sure what type of scanner you're using to watch fuel pressure, but it wouldn't hurt to verify it with a mechanical gauge before tearing into pump replacement - assuming that replacing the fuel filter doesn't fix it. Just a good double check, but based on your issues and that pressure reading, it looks like you have found the issue.

The fuel pressure regulator is part of the pump module on these cars.

Thanks for info, pump ordered, and going to replace this coming weekend. One thing tho.... Will the regulator be part of new pump? Or is it a separate part. I'd hate to start it up after pump replacement and find out that is it. Just replaced filter yesterday and it bogs at higher throttle. I'm getting pressure but maybe not enough. I couldn't get the dang gauge to work
