What does an ignition coil do?

Autoshop online Here is a synopsis of this link. Coil The coil is a compact, electrical transformer that boosts the battery's 12 volts to as high as 20,000 volts. The incoming 12 volts of electricity pass through a primary winding of about 200 turns of copper wire that raises the power to about 250 ( Full Answer )

Where is the Ignition coil?


Why would a 1993 Pontiac Sunbird 31 lose oil pressure when idling at proper running temp and then it returns at higher RPMs?

Answer . \nwell, oil pumps are power by the engine, when the engine is at idle its at its lowest rpm when you step on the gas the rpms get higher therefore your oil pump works faster delivering oil at a faster rate to keep up. oil pumps got a valve call the pressure relief valve and that valve ma ( Full Answer )

What is the ignition coil for?

The coil The igition coil provides high voltage to the spark plug, to provide the spark to ignite the fuel in the combustion process inside the engine. Likely, you know that most cars only have 12 volts that run all the functions in a car. But 12 volts is not enough to provide a spark across the e ( Full Answer )

What would cause the ignition coils to repeatedly fail in a 1996 Pontiac Gr Am 2.4?

Answer . \nReplacement coils must always be the same basic type as the original and have the same primary resistance as the original. Using the wrong coil may damage other ignition components or cause the new coil to fail. \n. \nYour engine is experiencing repeated coil failures, and it may be ( Full Answer )

87 323 sw stalls at idle and hesitates during acceleration and in gear idle is irratic at stoplight.In park or neutral engine runs rough in lower rpm but fine in higher rpm. Fuel filter or pump or MAF?

\n. \n Answer \n. \nIf you have never changed your Oxygen sensor, this is most likely the cause of the problem; the symptoms you describe are attributbale to a failing or dead Oxygen sensor. I assume the car has recently been tuned (including a new fuel filter) and the problem persists.\n. ( Full Answer )

Why does 3.0 l idle runs rough the fine at higher rpm?

Check the length of white vacuum line under the hood that look as if it comes out of the A/C package as it is a direct link to the timing modulator. It only takes a hair line crack in a vacuum line to cause chaos in the idle circut, but when the motor speed is above idle a small crack may seal itsel ( Full Answer )

I have a 92 dodge stealth. it burns oil at idle but seems clean at higher rpm. it could be valves or rings but is there any known issues that might be an easier fix?

Mine did that, was told to buy a bottle of Lucas (got it at advanced auto) took about a week but ended up working.. My car was same way-had to put new catalytic converter on it and sensor.Don't use high octane fuel either cause it will just blow out the muffler , it's bad for the car to use high oc ( Full Answer )

What is the normal engine idle RPM?

A typical idle speed for a normal car engine is 600 rpm to 1,000rpm. It is higher for buses and motorcycles. RPM stands forrevolutions per minute.

Will bad ignition coil cause oxygen sensor to fail?

Yes, a bad ignition coil / misfire will cause an unburned mixture of gas/air to go into cat converter which will than combust in it and cause damage to either catalitic converter, oxygen sensor(s) or both. J.Dropic

What causes a ignition coil to blow?

Why is the steering on your Chevy truck extremely hard at idle and a little easier when rpm is higher Should you replace the pump?

It depends: does your truck have power steering or manual. Keep in mind that while driving a car with speed, power steering or manual, much less movement needs to be made on the wheel to make a bigger turn adjustment. If you have power steering, and it is hard to turn at any rate, check the fluid, b ( Full Answer )

What does the ignition coil do?

Ignition coils Ignition coils are very rugged and reliable, but can fail for a variety of reasons. Heat and vibration can damage the coil's windings and insulation causing shorts or opens in the primary or secondary windings.

What is wrong with My 94 accord that is not running the coil is fine-gets spark replaced the ignition control module car turns over but does not idle?

Check your fuel pump pressure. An easy way is to crank the car over and then loosen the bleeder screw at the end of the fuel rail (assuming it's common-rail fuel injected) and fuel should squirt out. If it doesn't, you have insufficient fuel pressure and should first change your fuel filter, and if ( Full Answer )
