2006 pacifica wont idle on start up after head job
Hello I just finished rebuilding the heads on my Pacifica it had a bad head gasket two burned intake valves and a bad intake manifold gasket. I went to turn the car on yesterday after triple checking everything was connected where it should be and the car wouldn't crank. I took apart the ignition cylinder assembly and found the plunger that actuates the ignition switch to be broken. I went to the dealer for a replacement part and they gave me the wrong vehicles ignition switch actuator so instead of spending more time going back to the dealer I decided to test starting the car with the key in the ignition cylinder turned to on and using a screw driver to turn ignition switch. The car started right up and instead of revving to an idle like any other car would start or like this Pacifica did before the head job it just conticontinuously revved in a pattern like follows... Vroom vroom..vroom vroom.. vroom vroom and would die. Or it would do two sets vroom vroom.. vroom vroom and die or once vroom vroom and die. one time it even went vroom vroom so many times before dying I lost countw. All the while it was blowing clouds of white smoke which was the left over coolant from the initial bad intake gasket where it literally poured out of the exhaust.my brother suggested replacing the oxygen sensors that I had not done so I did but it made no difference. Any help would be greatly appreciated.
