1990 F150 Codes
Hi, I am new to this forum as I just bought a '90 F150 4x4. I noticed that the check engine light only comes on after about 5 minutes or so of driving so I ran and looked up the codes and I got 67(neutral/drive switch circuit open), 32(egr positioner sensor below closed limit), and 41(oxygen sensor circuit indicates system always lean). Can anyone tell me how to fix these or what they mean? Thanks.
