My 95 bronco 351w is idleing to fast, about 1200 rpm. I can kick the throttle and make it come down but all i'm doing is making the butterfly valves in the throttle body jam shut. There is still vacuum in the throttle body trying to open the butterfly vavles. So when I step on the gas and let off normally, the vacuum holds the butterfly vavles open just enough to make it idle high. When I disconect the idle air control vavle it idle's fine, about 700 rpm. I've replaced the idle air control vavle, this is what creats the vacuum in the throttle body, and senser twice. So I know they are ok. So for some reason the cpu is telling the idle air control vavle to creat to much vacuum in the throttle body. Weird thing is when I start it, it idles high for 20 seconds then idle's down on it's own to where it should be. Vary little vacuum in the throttle body. But as soon as I step on the gas padel, the vacuum goes up and stays there. It's kinda hard to hold her back at stop light's, keeps wanting to climb up onto the car in front of me. Hay that would be kinda fun. Well, any suggestions would be helpfull! Thanks. Ed_Edde_&_Eddie_Bauer |
