No, I was thinking about the plugs also, I guess /or would the plugs make the idle run at normal 600rpm and surge to 900rmp when backing up or having the break on at stop or idleing in park. it only does this when the DJ is warm. and it does it intermittently aver 5 secs. I guess it wouldn't hurt to remove the plugs. do I have to install the same plugs as the one on the DJ or can I just get cheaper ones. Also would the PCV value also make this happen . i don't think the PVC value has ever been changed.
