thanks for trying to help...but it wasnt the jeep with the problem ..im was my dumb a$$ lol

so aparently towards the bottom of the throttle body..theres a rubber thing with 2 tiny holes..and a hose went to one of them..and with my luck..i had put it back in the WRONG hole.. lol
now that im officially done with installing the 703 injectors..i highly recomend it..its idles SOOO much smoother..and the acceleration from dead stop is better..
