Poor mileage S90-V90 1998

Dan:
Good advice.
Plugs were replaced about 20K miles ago and indie shop said they looked good.
T'stat replaced 10K miles ago because the temp gauge did not get up to half way.
Indie shop showed me the failed unit and why it failed.

On the vacuum thing, last spring I pulled the hose off the fuel pressure regulator and it made no difference in mileage or performance. Big surprise! This is around suburbia and some interstate. High vacuum should lower the pressure and low vacuum should have raised it. Pulling the hose set the vacuum to zero. I would have changed it out but the indie mechanic suggested waiting. My car uses the expensive one.

All vacuum lines were checked at the time and found to be OK.

Maybe I will try the FPR replacement.
