    Re: How to check for a faulty FPR (Fuel Pressure Regulator) and replace it

    I just thought I would chime in and note that my 99 Deville had a faulty FPR, but it was not leaking fuel when I did the vacuum test. I did have all the symptoms: Surging when idling - seemed like the car would drive itself. Poor start when warm, and a couple others I cannot remember. Put up with these issues for 2 years, as it was on and off at first, and cleaning the TB seemed to help, but eventually I spent a few days of research and thought I would give it a shot.

    Replaced the FPR and it has never been better.

    my .02 cents.

    Many members go back and purge old pictures from the forums - Look in the proper engine forum or the specific vehicle model forums.

    If you reduce the file size and upload pictures from an online service they should remain forever; CF has a 20 mb limit on attachment filesize, thus the need to occasionally make more room .......

    For you, this might work - http://lmgtfy.com/?q=cadillac+forums...+regulator&l=1
