Hi guys. Sorry if I didn't get this in the right area, it's been a while since I needed any help! I need to know how to pull codes using the CEL. I know I did this before because that's how I verified I had a bad CPS. I've never had a scan tool and would rather not drive all the way back to town to get one today. When I was driving in this morning the truck (97 F250 7.3) would buck and idle rough and the CEL came on several times. It would always restart and run fine until it started to act up again, got worse as it got warmer. I replaced the CPS myself 2 years ago for this and never had the issue come back. I took it in for the recall less than 1000 miles ago and I suspect they one they replaced it with is as bad as my original one. Does anyone remember how to pull the codes using the CEL? tried cycling the key 5 times, and searced for 30 min on the web. Everyone says use a scanner but I KNOW I did it somehow before without one. Thanks in advance!
