I am having problems with my 94 ram 1500. the check engine light is on and the codes that flash are 12, 21. It idles rough and didn't think that the O2 sensor had much to do with it and found that a common problem is the iac sensor. I replaced that and it still idles rough. now when i check the codes it flashes 21 twice??? any recommendations?

Get a decent scanner, one that can do both OBD1 and OBD2 with live data, even though the live data will be severely limited on OBD1 it's better than flash outs. Flash out codes can be misleading or even wrong.
