Question about 1994 Cadillac DeVille
I have a high idle problem in between 1500-2000 kickin out a trouble code of po27
I am not sure if this will help you but PO27 is listed as "Open Throttle Signal Switch" which could mean that your throttle position sensor needs replacing. Although with Cadillacs, it could mean anything. I hope this helps...
