SOURCE: Service Engine soon light, codes P0301 and P0171, replace plugs

Hi,, Well the service engine light comes on when your car needs to be tuned up, this happens when the timing belt needs changing or nearing its life span. Basically it involves changing the belt (optionally >) engine oil, transmission fluid, radiator coolant, fuel injection and throttle body servicing, changing gas filter, air filter etc. Its to prevent damages to your car. After its serviced the mechanic will need to clear all error codes and reset the cars computer. Clearing the error codes is done with a diagnostic tool, to reset the cars computer , remove the negative battery pole and press the brak as far as it will go, wait 60 second release and reconnect the battery pole. Some vehicles may need to be caliberated if it has an electronic throttle body system

I have changed the plugs and wires ignition coil and cleaned the fuel injectors on my chevy aveo 2006 and it still had misfire codes on cylinder 2 and 3. what could it be? My check engine light burned out...

I would doubt that 2 injectors have gone bad at or near the same time. Low compression very well could be the issue, but you stated the car runs fine. Did you reset the codes with a scan tool? If not try that and then see if the codes return. I would check the integrity of the coil to make sure it is strong enough and getting good spark to the plugs. #2 and#3 cylinders use the same coil just as #1 and#4 use the same coil.Good luck.

Whats the proplem ifthe spark plug is wet with petrol

If the plug is wet with fuel, it is an indication that the plug is not firing properly. Possible causes? Distributor cap, rotor, points/inductive pickup, spark plug wire or the spark plug itself. If you or a friend, relative, etc. has or has access to an inductive pickup timing light, connect the light to a power source and the inductive pickup to the plug wire of the "wet" spark plug. Start the engine and observe if the flash from the timing light is relatively constant in its frequency or is it erratic and sporadic. If the latter is true, check the distributor cap, rotor, distributor points/inductive pickup and plug wire. If the former is true, remove the spark plug and check the compression against other cylinders. If compression is good, replace the spark plug with a new one. If compression is lower than others, the air/fuel mixture in that cylinder is not being compressed engough for combustion, leaving the spark plug "wet". To learn the cause, put a teaspoon of motor oil in the spark plug hole, and recheck compression. If it doesn't increase, you probably have a valve or head gasket problem. If it does rise, you probably have a piston ring problem . Good luck

#4 cylinder misfire

This is a Central Point Injection system. He could not check the injectors that easy. You need to get a thermal camera, or a temperature gun. Take a look at the temperature of the exhaust when the van is running. You will see that the cylinder #4 will be cool compared to the rest. Also you will see that cylinder #4 spark plug will be White in color, when removed. The electrodes of the spark plug will be white. That is a lean condition. That injector is bad. You will need to pull the intake manifold and replace the central point injection system as a whole. AC DELCO Central Port Fuel Injection for Silverado Sierra Express Savana...

I have good plugs & wires,coils,new EGR.Still getting that code(P0304) do I need a new O2 sensor as well

P0304 is a #4 cylinder misfire. Swap the plug, coil and wire with a different cylinder to see if the code changes to that cylinder or stays with cylinder #4. If the code stays, the fuel injector will need to be replaced. If the code follows the components you changed then your problem is in the components and you can do further swaping of each indiviual component to determine the bad part.

Cylinder 5 missfire

On the 3.4 liter V6 the #5 cylinder is on the driver's, firewall side. The #5 cylinder on the 3.8 V6 is on the driver's, radiator side. 
Check the spark plug wire and replaced if needed and also the spark plug, also if may be a good thing to add fuel injector cleaner to the gas tank for the next few fill up to clean out the fuel injectors just to make sure that it's not a dirty injector problem and also replace the fuel filter just to make sure that the fuel pressure and flow is adequate for proper fuel injector operation.
A good fuel injector additives is the Lucas fuel injector, the price is unbeatable to the amount you get. Just follow the instructions on the bottle and hope this will fix the problem. Keep me posted, be glad to help you get your car running 100% soon.

93 oldsmobile quad 4 2.3 one piston is not working wet spark plug

If you have a stethoscope, listen to the injector while the vehicle is running, it could be stuck open. If you hear it pulsing the same as the rest of the injectors, then unplug it, let the engine run so it can get all of the unburned fuel out of cylinder (you said the plug was wet), take the plug and coil from cylinder number three, install them in cylinder # 4, put the coil/plug from 4 into 3, reconnect the injector, and see if the problem moves to cylinder three. Next if the problem does not move to cylinder 3, then you have an issue with either the wiring to the connector at cylinder # 4, or you have a mechanical failure. Remove the valve cover, check the valve springs on # 4. make sure they look the same as all others. If so, turn the crank and further inspect them. If they are mangled, remove the head. It needs to be repaired, and check the piston for damage. You could also do a compression check to rule this out.
