How to do a compression test on a 2.2L Chevy Cavalier?

Let’s say that my 2.2L Chevy Cavalier gave me following compression values when I did a compression test on all 8 cylinders: The next step is to do the math: STEP 1: 175 x 0.15 = 26.25. STEP 2: 26.25 = 26 (rounded to nearest one). STEP 3: 175 – 26 = 149. ANSWER: 149 PSI. Any cylinder with this compression (or lower) value will misfire.

Why is compression value going up in GM 2.2L?

This tells you that the piston compression rings are worn out and thus the problem is in the bottom end (block) of the engine in your GM 2.2L. In case you’re wondering why, it’s because the oil you added has helped the piston rings seal better and this results in the compression value/pressure going up.

What kind of engine does a Chevy Cavalier have?

The common engine in the Chevy Cavalier is the 2.2 liter four cylinder. A few models have a 2.4 liter engine. Both engines use two oxygen sensors.

Do you need voltage to both sides of injector?

You need a “noid” light also known as injector pulse light. It plugs into the harness and you can see it flash as you crank the car. ok, maybe im not explaining it right, there is no pulse. with the key on there should be 12v at the coil and 1 side of the injector, i have 12v at both sides….

What happens when the oxygen sensor fails on a Chevy Cavalier?

The computer then adjusts the ratio of air and fuel to lower the pollution in exhaust. When the sensor fails in the Cavalier, the computer ignores it and makes its own adjustments, which can cause more pollution, less gas mileage or both.

Which is the hot side of the fuel injector?

One side is hot/12v the other side is ground to fire the injector. The ground side is controled by the ecu. The best thing to do is get a manual/wire diagram at hondatech.info: Honda service manuals and stat unplugging stuff till you find out what happens.

Can a fuel injector not receive the correct voltage?

It is possible for the injector to cause issues even if it is receiving the correct voltage. They can clog up, which will decrease the spray inside the cylinder. This, in turn, causes the fuel to not burn completely and will create a misfire.

Why does fuel injector not close when ECU fires?

chances are, your injectors are dirty and not compleatly sealing when the injector closes, thus flooding your cylinders by not compleatly stoping the fuel flow into the cylinders. you are suppose to have hot at both wires on the injector untill the ecu fires.

How is the spark fed to the ignition coil?

One cylinder is fed spark directly by the ignition coil. The other cylinder is fed spark thru’ a spark plug wire (high tension wire). OK, technically speaking, this type of ignition system is not a true Coil-On-Plug (C.O.P.) System but hey, if it kinda’ looks like a duck and kinda’ quacks like a duck who cares?

What’s the difference between NGK Ignition coils and spark plugs?

Can a spark plug be removed from the ignition coil?

Using a regular spark plug will give a false test result that’ll have you chasing the wrong diagnostic path/conclusion and in the process wasting time and money. Do not remove the spark plug wire from the spark plug or the ignition coil while the engine is cranking to test for spark. This method will ruin the ignition coil.

What do you call a coil pack ignition coil?

Professionals often use the term coil pack to describe any type of modern ignition coil. But, by definition, a coil pack is a group of ignition coils combined together in a single molded block. With this design, each cylinder gets its own ignition tower but shares its coil with a companion cylinder.

Why is there no spark in my ignition coil?

Note: If all of the ignition coils aren’t delivering spark, the issue is likely with the control side (primary side) of the ignition system, rather than a single ignition coil. An absence of spark from just ONE ignition coil points to a bad coil.

Can a spark tester jump the plug gap?

The issue is, it takes less voltage to fire a spark plug that has been removed from the engine than one that’s still installed. So, although you may have spark, it may not be adequate to jump the plug gap with the engine running. A quality spark tester, on the other hand, requires tens of thousands of volts to fire.

Where to find Vin 4 firing order diagrams?

Repair Topics > Ignition > Firing Order Diagrams > GM vehicles > 2.2 4-cylinder VIN 4 firing… Alldatadiy.com and Eautorepair.net are professional-grade shop manuals—period.

How many Sparks does an ignition coil produce?

A larger ignition coil can produce about 40 kV. These coils can be mounted on top of the spark plug, and are called a direct ignition plug. Coils can also serve two spark plugs, and are called the wasted spark system. The wasted spark system consists of one coil generating two sparks per cycle to each cylinder.

Where does the voltage from the coil pack go?

When the electronic control module (the car computer) sends the signal to the ignition control, the voltage is released from the coil pack through the spark plug cables to the spark plug.
