Not much left besides the pcm. Do you have a scanner so you could check to see if the pcm is seein rpm signal?

I borrowed a scanner, yes it is reading rpm. another question, the map reading at idle is 37 when I rev the eng to 3200 and let off the throttle the reading drops at 3200 to 17 then to 13 and then to 11. is that normal
