It's either timing or valves way out of adjustment if it isonly the 2 cylinder not firing try changing the coil pack for 1 and 3 with 2and4 then ifcylinder2and4 act up replaice the coil pack

What is the possible solution to a mis-fire in the 3 Cylinder on a 1996 Windstar GL 3.8L?

The most common problem is loose\bad spark plug or wire. If that doesnt fix then it is probably coil going bad.


What is the best way to prtevent carbon monoxide poisoning while boating?

Never be down on the water close to the engine exhaust port. Carbon monoxide is a heavier-than-air gas generated by incomplete burning. It is colorless and odorless, and kills by binding to blood cells better than oxygen does. Carbon monoxide poisoning is especially a problem for pontoon boats with outboard motors; the pontoons trap the exhaust gasses between the hulls, and the exhaust port is right at water level. If a child swims between the pontoons with the engine idling, he's running a real risk of CO poisoning, which is a nasty way to die.


Which graduated cylinder is more precise a 25 mL or 100 mL?

As far as sig figs are concerned, the graduated cylinder will yield a measurement that is both more precise and accurate than is possible using an Erlenmeyer (precision and accuracy mean different things in science talk). Erlenmeyer flasks aren't really intended to be used for measurement of volume, as the width of the flask at the point of the markings introduces lots of error as you try and eyeball the level of fluid within it. The narrow column of a graduated cylinder will allow you to judge volume far more accurately since a difference in the height of fluid in one of these will result in a lower overall difference in volume when compared to the Erlenmeyer.Keep in mind though, that just because a graduated cylinder contains a certain volume doesn't mean that it will deliver that entire volume to another container, since some of the liquid inevitably clings to the sides. This isn't a problem is you are simply trying to measure volume, but if you are trying to pour an exact volume into another container you need to use another method to do so. In this case your best bet is to pipette.


How does carbon cause this problem?

The 'problem' of 'this problem' is not understood.


Why does GFCI plug trip when exhaust fan is turned on?

That probably indicates a fault in the exhaust fan; either a motor winding has failed, or the fan is wired improperly. Just to amplify - The Ground Fault Current/Circuit Interrupter (GFCI) detects current flowing to ground that should instead be flowing in the fan. This means somewhere in the fan the Hot wire has an unintended path to ground and is a shock hazard. You should check the wiring to the fan (with power off) and make sure there are no bare wires that could be causing your problem and if you don't see anything obvious you should replace the fan.

Is the engine in the 1997 Chevy Cavalier the same as a 2003 Chevy Cavalier and can you put a 2003 engine in a 1997 Chevy Cavalier?

Well yes and no. Both have a 2.2 four cylinder if I'm not mistaken, but I don't think the earlier Cavalier's have the EcoTec motor. And you should be able to get the engine from the '03 into the '97 with no problem.


Why can you smell exhaust coming through the dashboard in your 1992 Volkswagen Eurovan?

You can smell exhaust because your exhaust pipes and exhaust system has worn out. As a result, the exhaust and carbon monoxide it contains leaks inside the van. Soon, it will not be a problem because the carbon monoxide will have killed all of you.


How do you know if the injectors not working on a f350?

Feel the exhaust manifold at each cylinder as it is running, if an injector isn't working the manifold at that cylinder exhaust port won't get hot. Some of those Ford diesels had a problem with the electrical connection where the injector harness passes through the valve covers.


What would cause water to leak out at exhaust manifold and tailpipe at same time?

A broken piston ring is the most common cause of water in the exhaust manifold. A bad valve in the cylinder head can also cause the problem.


Why does CHT cylinder head temp. peak come before EGT exhaust gas temp. peak and what is the relationship between the two that would indicate an engine problem?

combustion happens in the cylinder for the CHT so that is why temp peaks there first - then the hot gas is exhausted for the EGT - i would guess that a larger than normal difference between the temps would indicate a problem with gas flow, perhaps a breach or blockage in a cylinder or the exhaust system


When only one cylinder is working and lights. How come the second cylinder won't fire and run on both?

Basic trouble shooting. Start with:Compression check first.Is the spark plug good? fouled. Cheap, replace it if your not sure.Is the Firing order correct?Is there spark at that plug?Is there fuel at that Cylinder?Is the exhaust for this cylinder plugged?Is the exhaust valve stuck shut (Bad Camshaft)If all this does not track down the problem Start over at the top.


What is the problem with cylinder heads on ef-el falcons around 180000kms?

The problem with cylinder heads on ef-el Falcons around 18,000 kms is loss of coolant. Yet, there are?æno evident leaks. This is due to leaks are behind the exhaust manifold and can only be seen by removing the heat shield.?æ


Why does exhaust indicator remain lit whwhen there is no problem with exhaust vauxhall astra?

Because there is a problem, and you don't realise it!


What causes a Chevy 350 1977 camaro fresh rebuild that blows water out exhaust?

Is it water or antifreeze ??? It is probley condensation. If it is cold outside were your at then this is what happens. The exhaust system is cold and when you start the engine the exhaust heat flowing through the cold exhaust pipes makes the exhaust sweat. And it looks like water is running out. Engine is running lean. Needs richen up. If it is antifreeze it will be smoking real white out of the exhaust. And that would mean a head gasket is leaking coolant into the piston cylinder. That is the most common problem with a antifreeze leak causing white smoke. I have seen intake manifolds leak coolant into the cylinder head ( runner ) but it is rare that happens. I don't think you have a problem.


Will an exhaust leak at the rear exhaust port of a 460 ford engine burn a valve or cause other harm to the engine?

Yes, a prolonged exhaust leak will eventually cause problems with your cylinder head. The leaking exhaust is very hot and you can cause small cracks in the head if you don't repair the problem promptly. If you can hear the exhaust leaking, it may already be too late! Get it checked out soon!


Could an exhaust issue on a 4-cylinder engine cause it to misfire?

A misfire caused by the ignition system exhausts unburned fuel into the exhaust system that enters the catalytic converter and causes its temperature to rise dramatically. An exhaust issue could cause for cylinder 4 to misfire. The camshaft lobes, which are responsible for opening and closing the intake and exhaust vales, are another source for a misfire and rough running engine. The cam lobes for the No. 4 cylinder should be inspected to see if they have been worn down due to lack of oil or other mechanical problem. A damaged camshaft lobe will not allow a valve to open properly if at all.


What would cause 1996 Cavalier 2.4 to suddenly while driving start missing on two cylinders and when coils changed for it to be out of timing but one cylinder fires but others backfire.?

Since the Cavalier is out of timing, check the timing gears and belt. It sounds like the belt has slipped and is causing the base problem with the car.
