Help Cracking the Code(s)
Okay, please bare with me as I 
...
Lately I've been getting an intermittent check engine light. At first I thought it was because I lost my gas cap but even after replacing it I'm still throwing codes which disappear intermintently and/or once the key's turned off. Yesterday I finally caught and pulled them, and this is what I came up with:
The common thread seems to be the ECU after looking throught the trouble area for all the codes in my Haynes book. I did check the Air flow meter this morning and all its readings were in spec. Looking for other ideas/options on what to do next.

I got the same problem with my v6 3.0. I get this code 52 knock sensor. I checked the connection and it was loose. I cleaned it and secured it and the truck ran fine, but then it happened again, I'm about to replace the wire to the knock sensor and since I'm in there the knock sensor too. I know the wire is faulty, because when I mess with it it runs fine for a while until I hit a bump, the connector is broke. To replace the wire I have to take off the intake manifold, upper and lower so I decided to replace the knock sensor too. My truck is 17 years old, 1988. Check your connections they might be loose or corroded. Ketman

Ketman, thank you for the reply! This sounds somewhat logical since sometimes it will run just fine without the light and then all the sudden the MIL will glow like the sun and it runs really dawgy. I'll give the connector a once over. Thanks again.
