OK.....I am having the rough idle problem with my 2003 tacoma 2.4 L automatic. In the 2003 service manual located here:
http://misc.mmdsi.net/tacoma/tacoma-manual/ on page SS-30 it tells me the spark plug gap should (.043), but on page IG-2 in the service manual it tells me to gap the plugs to (0.31). I know this has been hashed over in the past. When I recently replaced my plugs I gapped them to 0.43 and the idle got rougher! DOES ANYONE KNOW THE PROPER GAP!

Thanks
Mike
