Question:

If my vehicles air intake is somewhat clogged and dirty, what symptoms should i be experiencing with the car?

My car shuts off after im driving and i come to stop and its on idle. Is that normal for air intake trouble? I was told cleaning it out would solve the problem, does that sound accurate to you car savy folks?

Answer:

Most likely it is a faulty idle air control motor/ solenoid An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or ECM (electronic control module) receives information from various sensors and will output signals to adjust the IAC motor in or out to adjust engine idle speed by controlling engine idle air. An IAC motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the IAC control motor to react slowly, either failure can cause the engine to stall at idle. An IAC motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the IAC control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak IAC motor. To check the IAC motor remove the unit, with the wires connected turn the key to the on position without starting the engine, the IAC should move in or out. If the IAC motor does nothing it has probably failed, replace it with a new unit and recheck system. Note: while the IAC motor is removed clean (use aerosol carburetor cleaner) the passages the IAC uses to control idle air speed, also inspect the IAC for a build-up on the seating (pointed) end and clean as necessary.

No you have a fuel delivery problem. Whoever told you that the intake was clogged is a ******* retardthey wouldn't be able to operate a toaster let alone fix a car.
Yes it is , actually is part of the maintenance of a vehicle around 75,000 miles to remove the whole intake system and clean all ducts, however in more than 30 years of experience I have seen only one person doing it and my self, the idle control valve also does have that kind of symptom you just describe , but is also part of the intake cleaning , actually I did it in my car about 4 months a go not because there where a problem just for maintenance and my car now is so smooth and quiet , with more power and Response , that when I use the remote start I can't hear the engine running I only know because my remote has an screen that tells me is running , also starts Right up and saves me gas as good as it was when new, I mean I knew all the advantages of cleaning it , but I just want it to share with you. good luck !!!
