I have a 99 cherokee sport (4.0) with 150,000 miles. Occasionally it will not idle. If I hold the idle myself until the engine warms up(5 min) then it will idle. I ran a scanner po 505 came up. I recently replaced the idle conrol motor but this has not solved the problem. What else can it be?

Just a few thoughts.
Did you disconnect the battery? You might need to reset the computer by disconnecting the negative cable.
Did you double check the connector and it's wiring?
Have you cleaned the throttle body and the IAC port?
Have you cleaned the EGR valve and it's port.

Have you cleared the code and had it come back?

Good luck and let us know. :)
