What would cause 1996 Ford Explorer to overheat then idle high and low?


Only a few general concepts, keep in mind that the exhaust gas recirculation (EGR) valve is an integral part of a vehicles emissions control systems. It operates under the premise of lowering combustion chamber temperatures to reduce the amount of pollutants created by the combustion process. Being closely tied to the combustion process, this valve's operation has direct effect on the overall performance of the engine. Poor or faulty operation of the EGR valve can result in several notable symptoms and leads to increased pollutant emissions.

Poor Idle: An improperly closing EGR valve will act as a vacuum leak, disrupting the correct fuel and air mixture, causing a lean mixture condition. This results in misfiring cylinders and poor engine idle.

Overheating: The basic function of the EGR valve is to introduce exhaust gases into the combustion chamber at specific and controlled rates, lowering combustion temperatures, and lowering pollutant emissions. An EGR valve that does not open properly fails to introduce sufficient amounts of exhaust gases, causing combustion chamber temperatures to rise, leading to overheating of the engine.

Poor Fuel Economy: A sticking EGR valve will not open and close at the proper rate, leading to a reduction in the efficiency of the combustion process due to the lean fuel-air mixture it causes. This results in the engine having to work harder to perform the same amount of work, requiring more fuel to do it. On-board computer systems can also try to compensate for this lean condition by introducing additional fuel to the mixture, further increasing fuel consumption.

Increased Emissions: EGR valves are designed to lower the emission of pollutants from the combustion process. This is done by lowering the temperature of the combustion process through the introduction of exhaust gases into the fuel and air mixture. Lowered combustion temperatures result in more efficient burning of the fuel and air mixture, and less pollutants in the exhaust emissions. An improperly operating EGR valve will not correctly lower combustion temperatures, causing noxious emissions to increase, which can cause a vehicle to fail emissions inspection.

Test cylinders compression and check if some fault code is stored in the PCM 9computer).

How do i tell if my egr valve needs to be cleaned or replaced? I have a 2006 Silverado LT 2500 HD 4X4 6.6 LTR. Diesel. Chevrolet makes two different model engines. LLY and LBZ i think, can you tell me...


The EGR valve recirculates unburned Exhaust gasses to your Intake in order to increase Fuel Efficiency and lessen Emissions. What are the codes on your truck? The check engine light comes on when a sensor is out of range, or failing, and a code is stored. Autozone, etc. can check your code for free.

WHICH MERCEDES BENZ WOULD GIVE BEST SERVICE WITH mınımum repaırs


Let the head rule the heart...the S320 diesel. The engines are well built with only the exhaust feed-pipe from the exhaust manifold to the EGR valve needing to be occasionally cleaned out. The Mercedes diesels offer surprisingly good performance, longevity and excellent fuel economy. The S500 is sumptuous but at a cost; the expense is like standing under a shower tearing up bank notes.

4d56 engine high fuel consumption


4d56 is a diesel engine, fuel, oil, air filter change definitely, regular oil change, check tyre pressure, etc all basic things u can do yourself, after all its no 40+ MPG modern diesel engine its been around for years and years and being used in courier van, pajero and delica, i have a Delica with 4D56 turbo and its loves drinking diesel like no tomorrow, run it on veggie oil like i do you wont worry too much about your fuel consumption.

Our 2000 contour starts missing and dies. It will


Try running injector cleaner like Lucas injector cleaner through the fuel system and also check the fuel pressure regulator. If the fuel pressure regulator is bad or the vacuum hose has a leak, that's where the problem may be. The other to is to try and clean out your EGR valve. A dirty or stuck EGR valve will give you the problems your described, Remove the EGR valve and clean it out with carb cleaner and make sure that the valve is not seized and can move. Good luck and hope this helps. Keep me posted, be glad to get your car running 100% again.
