I was driving the truck tonight and the SES light came on. :eek:

Code: P0089 -- Fuel Pressure Regulator something-or-other

I noticed over the past couple of days the idle flexed a bit, sounded like the A/C was on and cycling....

I know it's not a lot of info, but any ideas? Is this something I may consider fixing myself? About how much should it cost???

By the way, unfortunately I'm out of warranty, 110K miles...

Thanks in advance for any help!

Jeff :ro)

I had that same code pop up on mine and it turned out to be a bad fuel filter, I had the dealer vacuum test it and it was 4X beyond the allowable restriction range...Mine had a shoddy idle as well. Hope that helps.
