On the way home tonight my CEL was on which was no big deal cuz i know i need a 02 sensor...code 21... but for the heck of it i checked the codes again tonight when i got home from work...now i'm gettin a 12....21...and 34....WTF IS Speed control Solenoid circuits?!??!?! I'm stumped... i searched the forums and found nothing also...lol... thanks[&:]

 

The only thing I can suggest is to check out Das's sticky at the top of the forum for the sensor locations.

 

You must have cruise control, correct? Probably a vaccum line disconnected or a short somewhere.
