When my vehicle is idling it runs fine. If I turn on the defrost the engine bogs down, and almost dies. The engine drops to about 2000 rpm (normally idles around 5000) and the power drops from just above 14 down to almost 9. I thought maybe the a/c compressor kicking on was putting too much strain on the alternator. I replaced the alternator, and it is still doing it. I had someone tell me that it could also be the thermostat or the engine coolant sensor that is not working properly. I also recently had to replace 2 of the ignition coils. Not sure that they would have anything to do with it or not. I found a sensor just above the thermostat housing that had fluid in the plug that I think was coolant. I could not get the sensor out. I am not sure what the sensor is for. Any help would be appreciated.
have the same problem?
