Reed valves are usually in 2 stroke engines, they are a valve that controls air fuel intake on carburetors..
why asking?

What would cause 1996 Fprd Explorer to overheat theres no leaks in Radiator or hoses and i recently replaced thermostat.


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.

Hope this helps; keep us updated and

My 2000 lincoln ls feels like it has a misfire while idling @ stops. excelerates fine until it hits between 40- 50 mph. then has same feeling of the misfire or low power. then once it reaches over 50 mph...


Buy one new coil from auto parts store $59.00

Walk it one cylinder at a time

Why would you swap coils,obviously one
of them is bad.

The one you took out of #5,find it ,and put in the
new one there.

I would put in new OEM Plugs.
They are a special tip just for the LS
at least on ones newer than yours
They are NGK even though they have motorcraft
on the ceramic shell.

Clean the throttle plate and MAF with the two
CRC products for that

I wouldn't rule out a bad EGR Valve as another issue,
though not related to the misfire issue

Just replaced starter on 1996 k1500 5.7 v8. Check engine lights go on and off and it misses at about 50 MPH. It runs smooth at lower speeds.


One of the vaccum lines might be disconnected to the reed valve, It sounds like the emissions system is giving problems.
