First i would look for leaks in the intake boot. could also be caused by the idle valve.

Idle problem integra


check the MAP sensor (manifold absolute pressure). The ECM (car computer) uses that to keep idle at minimum 750 RPM. It's normal for it to run high when cold. These small 4 banger motors typically run hot, and they won't run right IF they're NOT running hot, ergo the idle is usually high when it is cold so as to cause it to warm up quicker. If the RPM's drop below 750, suspect the MAP sensor, &/or ECM.

First- lets change engine coolant sensor/ECT/ and you will be very surprised.Black head with four pins.Be very carefull when change it because there is pressure into coolant system.First-open slowly the cap of engine coolant tank.Then tighten again to safe coolant.Unplug the sensor,remove the pin and pull out the sensor.If the "O"ring/old one/ is still inside-take it out.

Does it run rough when stalling at 1000rpm or does it seem like the rev limiter is taking over (just revs and stope). If running and just stopping you man wanna have your ECU reflashed (common problem). If running rough you may have some other issues and need a diagnostic. Try going to your local auto parts store and having a code scan (its free) and see what codes if any are present.

Bmw 523i se heater blows hot and cold


Sounds like a thermostat sticking. Some things to do. First check coolant level is up and moving. Second (most likely), change thermostat. Very easy fix for backyard mechanic. Make sure to put thermostat in so water flow is correct direction. Look for arrow on side of thermostat. Next, is belt to water pump loose. Another easy fix in most cars.
