See what cylinder is loosing (if that's it) spark. Use a spark tester if you can, or remove plugs and turn it over with the wires on all of the plugs, grounded!

2002 toyota tundra wont stay running will start and die right away.


Throttle control motor? No, never heard of one of those. Possibly a Mass Airflow Sensor. It sits inside your throttle body on most cars and measures the airflow into the intake. When it gets dirty or goes bad it really messes your car up. it is either in your throttle body or between the air filter and the throttle body either way it will be pretty simple to remove and clean. If it is your MAF then try to clean it first with MAF cleaner. They do have a cleaner specific for that at the auto parts store. You can usually clean them and be alright. Could save you alot of money. Hope I could be of some help. Good luck

My 2004 toyota tacoma has a rough idling problems and I was told to replace MAP sensor. Now, would it be Mass air flow sensor ? Because I can not locate any info on MAP sensor of this yeat truck


Yes your truck is equipped with a mass airflow sensor (MAF). However, I would not just replace that because its running rough. I would begin diagnostics by first checking to see if there were any trouble codes in the engine to give you a clue as to the rough running condition. I would expect a trouble code to be present to support the descision to replace the MAF Sensor. If no codes are present I would suggest that you get the vehicle tuned up. (Spark plug replacement and throttle body cleaning and I would also suggest removing the idle control valve and cleaning the carbon and dirt out of it. Although what you were told might be correct I dont belive that is where I would start.

Shutsoff when you come to a stop or slow down and idles rough


Check the IAC sensor. If ok check TPS and MAF. Clean throttle body inside real good but let air out before putting air intake assembly back on or starting.

Clean/Inspect Intake, MAF sensor, IAC valve for proper operation. Also check for vacuum leaks within the air intake hose and intake components. Hopefully this helps

Need to locate toyota aurion/camry iac valve


the MAF sensor is between the air filter and throttle body. the idle controll is at the throttle body.  Its located on the throttle body on the left side. Follow the air intake to an intake manifold which sits on top of the throttle body.

Maf?/ missfiring


have the map sensor checked to see if it is within range you say you have codes maf make sure all clamped duct work is tight and not loose clamps .iac motor clean bore if the pintle gets stuck will cause rough idle hesitation even no start conditions scan tools only test the idle air control valve motor not the bore that extends to block varnish gets built up on the pintle and in the bore wich binds the in and out operation
