Re: OBD II Gurus Help!!
I'm pretty sure you're going to need a scanner to diagnose this. Careful though, I borrowed a scanner for my '95 Ranger not too long ago when my check engine light came on. Said I needed a "Purge Control Valve". Figured out what it was, got a new one, slapped it on, and cleared the code. Code was back in a couple of weeks. Fought with it for a couple of months before calling Ford and they told me they always replace another valve in the same line at the same time. Wasn't mentioned in my books. When you do get a scanner and find the code, it's a good idea to make sure that there is only one part you need to replace. I ended up hassling with it for nearly three months before I broke down and called the dealer. Took them 2 minutes on the phone to tell me the problem, and me less than five to put te new piece in at the dealership.
Good luck with it, and please let us know how it comes out!
