I currently drive an automatic 1991 Nissan Stanza XE with a KA24E inline 4 cylinder engine. I've always noticed that when I am at a stop the car sometimes surges when it idles, but sometimes it is perfectly fine. When I use any electrical component, like the AC for example, the car idle lowers to about 500 RPMs at a stop. Another thing I have noticed is when I park and go to roll the power windows up that if I hold onto the switch after the window is all the way up the idle surges too. I find this car to be really weird because when I'm driving it runs perfect. Since we got the car we have replaced the Idle Air Control, Throttle Position Sensor, cleaned the EGR valve and the Mass Air Flow Sensor, but still there seems to be an issue when I use anything that needs electricity. I also tested the alternator. I turned the car on and unplugged the battery, the car kept running so I don't see it as the issue. I think a wiring harness might be starting to go, but I don't know if that's the problem or if it could be something else.
have the same problem?
