87 ford bronco II idling and power problem
\015 My bronco II has a 2.9 liter engine. On the first start of the day it wont idle and you have to give it gas as you would a car without a choke. I have replaced every sensor on it, except the O2 sensor. Once the engine starts to warm up it idles on its own but surges up and down till it warms up more and then the surging stops. It doesn't have any power to accelerate above 45. I bought a scan tool, but I can't find the single wire plug in to hook it up, only the large one. I have replaced the plugs, wires, distributer cap and rotor on it also. The air filter was replaced a few weeks ago.\015
Check the i.a.c. (idle air control) valve near the throttle body, it fixed my low idle!
