Thanks. Yes, I learned that today! Went by AutoZone to have them hook their code reader up cause I was concerned that the reader I was using was an older model that wasn't updated. It also read P1504 as well as P1507. With that when we checked under the hood for wiring issues we saw immediately (I hate this part!) That an animal (mouse, rat?) Had chewed one wire nearly in two and was working on the other on the IAC. I don't know how I managed to skip this step in the first place since I've been in maint all my life. Boy, did I feel stupid! Anyhow, temp fixed the wiring on the connector tonight; the truck started right up, idles fine, etc.
Thanks for the tip on the carb cleaner; I was a bit concerned that I messed up after reading some other blogs. I'll probably pull the throttlebody and MAF and give em' a good cleaning.
