Volvo 850 - 189K -- Checked all the vacuum hoses I could find for holes or bad connections to nipples -- and to make it even more confusion it's not consistently occuring, but -- when I am turning such as being in the right line at an intersection and tuurning, if I "step on it" there is a slight hesitation and almost loss of power that lasts until I either complete the turn (wheel straightened) or I floor it even more and power resumes. Weather is conducive to do some preventive maintenance and I'd really like to get to the bottom of this. Thought about fuel filter, engine mounts look like they could stand replacement. Just wondered if anyone had encountered something like this before I start pulling stuff. ADDITIONALLY, I had all four brake pads replaced by a neighbor -- ceramics on the front, O'Reilly $35.00 specials on the back, and my rear brakes are squeaking. I also noticed that just as the vehicle comes to a controlled stop using brakes, there is a noticeable "click" first on the right rear side and then a half/second later, on the left rear. Suggestions on troubleshooting greatly appreciated on this issue as well.
