SOURCE: idle air control

all the sudden the check engine light came on and it started to idle funny and dying at stops. I had a diagnostic done on it and changed out the idle air control valve but it doent seem any different. and the check engine light is still throwing the same code. we adjusted the idle up so i could drive it with out it dying but it is still acting funny.

You'll have to remove the throttle body to replace the idle air control (IAC) valve. First, disconnect the negative ground cable from the battery. Then remove the vacuum line and air duct intake. Then disconnect the IAC and throttle position sensor (TPS) electrical connections. Remove the coolant hoses that are connected to the IAC. Disconnect the throttle cable from the throttle body. Now, remove the 4 bolts that hold the throttle body to the manifold and remove. Be careful with the gasket located between the throttle body and manifold and replace it in the same position. On your clean work surface, turn the throttle body over and remove the 4 phillips head screws holding the IAC to the throttle body. Clean the parts with a dry cloth but do not use solvents on the IAC or TPS. That's it!

Hi, the "dirt" that clogs your EGR valve and intake manifold is not dirt in the traditional sense. The dirt in this case is carbon buildup from your engine and emissions. When the carbon builds up to a certain point, it hardens and forms a residue. This residue will ultimately clog your intake manifold and EGR valve, stopping them from functioning properly and causing the rough idling and stalling.

Carbon buildup is caused by not burning all the gas going through the cylinders. This can be caused by many different things including using bad gas, driving around in the city too much, and not having enough spark in the engine, but the main cause of carbon buildup is driving too carefully. Driving slowly and safely and carefully every single day puts a lot of pressure on the engine. Driving like a maniac isn't good for your vehicle all the time either, but occasionally it is good to break out of your normal rhythm.
Unless there seems to be a major problem try to keep the car at a steady acceleration until its ride is nice and smooth. You may need to stop the car and then start over by punching the gas pedal again. This way you don't accelerate past the speed limit allowed on the road. It is the rapid acceleration part that burns off the carbon, not the speed, so don't risk a speeding ticket. When the vehicle seems to respond to the gas pedal easily and undergoes no more choking, you've gotten rid of the excess buildup. Try to gun it occasionally each month to prevent more carbon from building up. A few minutes of consistent acceleration will keep your engine nice and clean.


If you have a lot of exhaust coming out in a steady stream and it is blue or black, stop accelerating immediately. There could be something wrong with your engine and you don't want to aggravate the problem by trying to burn off the carbon. Different colored smoke means different things. Blue, usually there's oil in your gas mixture. Black usually means you have bad valves in your engine. Take your vehicle to an auto shop and tell them about the color of the smoke and the amount. You probably have bad rings or need a valve job.

My 2004 Mits Galant air conditioning is not working correctly. First of all, when the AC level is on 1 or 2 it doesn't blow at all. It blows on Levels 3 and 4, however the air is not cool at all. It is...


problem one the blower positions first it could be the blower resistor or possibly the switch second problem no cool air there is a heater shut off valve under the dash on the right side of the radio if you change the temp control from cold to hot and hot to cold and hear a clicking ,grinding noise this valve is bad and not shutting off the hot air to the system making your a/c feel warmer , or a/c system has a leak somwhere and will have to be recharged and traced to repair it

No heat or cold air will come out of my2004 Mitsubishi Galant. I took off the dash panel behind the glove box to get to the Blend Door Motor, but after turning the air from hot to cold at various speeds,...


Does the air blows through the dash board vents. Does the selector is functional, that means you can force the air stream through wind shield, or vents or down to the legs. If these things are OKthen check CONTROL PANEL.
Remove the trim plate surrounding the center instrument panel. Detach the electrical connectors and remove the control panel.

Bad idle air control valve. Most likely needs to be replaced. I'm guessing you have around 125K miles on your Galant, right? See other posts for solution.

SEL code P0401 (2004 Mitsubishi Galant 2.4L)


Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

Code P505 - stalls when warm


Definite signs of intermittent vacuum leak downstream of the maf. Check for leaks from the air cleaner to the throttle and all hoses on the intake manifold. Also check for leaky intake manifold gaskets.
