WJ High Idle Switch
I may be getting a 99 WJ Laredo (4.0 I6) at some point over the next year. Out of curiosity (and because I can't find any answer to this), is it possible to add a high idle (or "extended idle") switch to one of these, like on the 4.0 XJs? If so, how complicated would it be? If there is no simple way of doing it, is there a way to trick the TPS to raise the idle to about 1200rpm on command?
