SOURCE: Our 2005 Chrysler Town and Country van dies at

My suspicion is that your egr valve is sticking slightly ajar which will cause the engine to falter at idle speed. The valve is located near the throttle body air intake at the end of the engine, mounted in a small diameter pipe that recirculates exhaust gas from the rear cylider bank exhaust manifold back around to just below the intake manifold where the air from the filter enters the throttle body. The exhaust gases have some fumes that can plate out a crud on the valve stem and thus keep it from closing tight when you are start or at idle. That makes for a too lean mixture so the engine stalls. The valve proper is mounted horizontally with the stem visible in a space between the body of the valve mounted on the pipe and the round top of the valve which is flanged and so if you look carefully you will see a metal rod (stem of the valve) with a slot around its circumference. You can take the tip of flat blade screwdriver and insert it in the slot and then lever the valve back and forth to check if it is moving freely (against spring action in one direction) or not. If it doesn't seem to close easily with the help of the built-in spring, then I would spray the base of the stem with solvent from a pressure can (such as WD-40 or carb cleaner) while moving the stem back and forth.

SOURCE: car keeps dying when giving gas, idles low, dies

Problem could be either to much air OR to much fuel in inlet manifold
If you have a pipe broken or come off the inlet manifold from either a breather from the engine that could cause it, or a problem from the fuel tank such as a fuel filter on the line from the tank to the engine,or Air Filter needs cleaning etc, or even a air leak in the Inlet manifold gasket.

2006 Impala 3.5L v6 intermediate throttle response issue


It's a gm vehicle, but, I don't know year and model? Any applicable trouble codes.
If fuel trim is negative, low speed and load, look for fuel pressure or injector leak. If problem only on bank 2, then check that bank.
Use a gage and check proper fuel pressure, then with key off, see if fuel pressure holds for a bit. If it drops like a rock, check for fuel leak. How long since a tune-up?

my guess is the wheel bearing. jack the rear tire off the ground and try shacking the tire. if you have any play your bearing could be bad.did you hear a hum from the same wheel. wheel bearings will hum before they start grinding

Toyota prado idling speed


Yes, it can be completely normal, engine idling RPM's will have various factors that affect them such as temperature, altitude, oil level. In all cars the RPM's will change when the compressor for the AC is activated.

My MAzda 2003 MPV ES.The evap and EGR still incomplete, need reset on the monitor- drive test; everything else passed the smog. no codes show on scanner. FEw months ago, I chage the battery, but I was told...


Here is the procedure for allowing system to run each of the separate mode tests.
EGR : Start engine and warm up completely. Make sure all electrical loads are off (A/C headlights, blower fan, and rear window defroster) Accelerate to between 49-57 mph and hold a very steady speed for 1 minute. Decelerate to a stop and turn off engine.
EVAP : Ensure Baro pressure is 21.3 inHg or higher, Intake air temp is 41-95 'F, Fuel tank level is between 25-75%, Battery voltage is 10.9-14.6 volts. Start engine and idle for more than 10 seconds then turn key to off. Leave vehicle to sit for 5 hours or more. Start engine and race to 3500 rpm to warm up completely the idle for more than 15 minutes. Accelerate and then drive vehicle at very steady speed between 40-50 mph for more than 5 minutes. Stop vehicle and turn key to off. Leave vehicle undisturbed for 20 minutes or more.
When I say steady speed in the above, try to keep dead on to a set speed to help ensure the test is run. Especially for the EGR as this is when the test will be performed and if speed/rpm is not very steady then test will not be performed. The Evap test will be ran during that final 20 minute or more sitting period (or should be anyway).

High idle/low idle pattern


This issue is caused by the egr valve being stuck open, more than likely. Just remove it and clean the plunger on it. Also clean out the two ports that are in the intake. Check out saturnfans.com for more information. I hope this helps.
