Hello, so as the title says I have a idle problem with my 04 WJ. It won't start unless I give it gas as I turn the engine over. Once started I habe to keep it throttle to about 1 rpm. Once the jeep is warm it will stay running but with rough idle.
Things I have done. New fule filter, replaced all fule injectors after Code for miss fire. New pully belt. Replaced the throttle position sensor. And clean the throttle body and idle air control valve. "May need replaced?"

I had a bad squealing coming from the belt and that's why i put a new belt on but i belive its my water pump the squealing is still happening. Would a bad water pump cause bad idle? I have spark plugs just have to install them.

Again my problem is won't start cold unless given gas. Won't stay running till its warmed up. Once warmed it will run and turn over with out gas help.. any ideal?
