It could be the EGR valve and a bunch of other things. Your truck is new enough it supports OBD-II. You'll need to get the trouble codes read from the truck's computer and that will tell you more information about where the problem lies. Don't guess, get those codes and do a proper diagnosis. You can look up the codes at http://www.check-engine-light.com Good luck!

How do you fix an idleing problem on b2300 mazda truck?


What kind of idling problem ? An what year Mazda ? Idle is controlled by the engine computer via a IAC motor , idle air control valve or motor, what ever Mazda calls there set up ! Or if a fairly new vehicle, they use drive by wire or electronic throttle control . With the idle air control set up passages get plugged an don't allow enough air to by pass the throttle plate causing stalling problems . A vacuum leak can cause a ruff unstable idle an stalling also . A dirty throttle plate can cause idle problems as well ! A scan tool ,not a code reader is a very use full tool to check engine data parameters. With the scan tool you can view idle air control counts . To see if the engine computer is actually controlling the idle air control valve . Idle Air Control Valve

Also an engine misfire can cause idle problems , also clogged fuel injectors can as well . A good diagnostic technician would start with hooking up a professional grade scan tool , checking for DTC'S - diagnostic trouble codes , misfire data , engine sensor data , IAC counts !

What could be cause of cold weather stall and rough idle until engine warms


Check your EGR valve and system. EGR should not be on when engine is cold, if its on the car will run as you describe.

I have a 96 vitara and when I turn the lights on the revs drop to the point of neally stalling, I have replaced the battery, and it is charging well


head lights.? on?
hot or cold engine, ? both?
i guess? you are parked, and in neutral, and the engine stalls.
the #1 reason for stalls is a stuck open EGR main valve. clean it.
there are other reasons, but above must be good to proceed.
others.
motor running way lean, diagnose that. use a scan tool , you in USA?

Oxygen sensor problem on mitsubishi outlander 2004


If the car has a check engine light on you may want to have the code checked, as this may point you in a direction as to what is causing this issue.

It could also be a bad EGR valve if the vehicle surges.

Hope this helps you out,

I have a 1995 lincoln towncar. It runs great until it warms up it. Then it starts to sputter and stall, I have done plugs wires and coil packs to fix a skip in the motor. That worked, now I have the new...


Try replacing your Idle Air Control valve. I am a former Ford tech and have two LTC's a 94 and a 96. I have had to do this job on both. When they get up in miles, the IAC valve gets carboned up and can't adjust the air/fuel intake mixture under load. If you still have a stalling issue after that, then you will probably have to replace the EGR valve as well. But it is very important that you start the engine with the old EGR valve removed so you can blow any carbon balls out of the EGR passage before installing the new EGR valve. Otherwise you will just end up plugging and ruining the new EGR valve and have the same stalling issue. Good luck!

How to remove and inspect throttle body on 1992 mazda miata


Things that make your engine do what it is doing.

1. Vacuum leak
2. EGR valve

Find the vacuum leak if there is one.. and check the function of your EGR valve.

A functioning EGR valve with an ORAL vacuum line suction test will cause the engine to stall / die when suction is applied to the ORAL external line.

Even if it passes the ORAL test... it can still have carbon build inside the plumbing that does not allow the seating pin to fully seat and the engine will surge or be hard to start when warm.

So check / listen carefully for vacuum leaks and check the EGR valve.

Car can stall in warm weather


Most likely if it is temperature related you may have a temperature sensor that is failing. The sensor may not be reacting properly to the actual temperature and causing the engine to run rich in warmer weather when a richer setting is not required.
You could have a sticking injector or sticking EGR valve or a faulty TPS switch, all can cause a rich condition and a poor running engine.
Is the service engine light on or come on at some point?
I would start by having the car scanned for trouble codes. You can have the scanned at no cost to you at your local Auto Zone or Advance Auto Parts. Write the codes down and respond back.

Only runs ruff during park and idle.


Your EGR valve shouldn't open up during idle or the engine will run rough and may even stall. Remove it and clean the plunger and port with a wire brush and some carb cleaner. Test the diaphragm with a vacuum pump. If it doesn't work after cleaning, or the diaphragm is bad, buy a new EGR valve.
