Re: oxygen sensor
Gotcha, I have been saying since I bought the truck 20000 miles ago that I would wait until the fuel pump died before I would change it. Maybe this is my sign... sounds like i need to do some fuel pressure testing. Also one thing I forgot is that when it idles sometimes it is rough and drops to maybe 300rpms, then kicks back up to 500. I attributed this to the SES light problem. the code I got was P0171 by the way. Thanks for the help, I really appreciate it!
