Jerking bad when driving replaced coil lead plugs ok coil lead sparking outside coil

Hi patricia, If you have a faulty coil and your car's running rough to find the faulty coil just pull a spark plug lead off and start your car, If it runs (ROUGHER) than before then that coil is ok. Turn the car off and replace that spark plug lead back on to the spark plug. Repeat with the next spark plug lead and so on until you start your car and it runs the same as if THAT spark plug lead is on or off, NOW TO MAKE SURE THIS IS THE FAULTY COIL, Put a spark plug into the spark plug lead that's off and earth it to the motor or body (it has to be touching steel), Start the motor and if that's the faulty coil the spark plug won't spark I hope this helps.....

Mate your car runs rough ok, To find the faulty coil just pull a spark plug lead off and start your car, If it runs (ROUGHER) than before then that coil is ok. Turn the car off and replace that spark plug lead on the spark plug. Repeat with the next spark plug lead and so on until you start your car and it runs the same as if THAT spark plug lead is on or off, THAT'S THE FAULTY COIL.... I hope I haven't wasted your time.....

ignition module that sends signals to coil, check crank/cam position sensors as well as map sensor.

Check the condition and operation of the following:
1) Fuel pump and filter2) Spark plugs, leads and coil(s)3) Air filter
Those are the more common issues associated with this type of fault.

bad wire?bad coil?

The spark and fuel system needs to be inspected.--------- The spark plugs are getting fouled or very loose, can cause sputtering problem.Inspect the spark plugs and coil packs.The spark plugs gets power from coil pack.If the spark plugs are very old and dirty, then it needs to be replaced.--------------- The **** problem also relates to faulty worn out spark plugs or clogged fuel filter or low fuel pressure or problem with ignition coil pack.----------- When coil pack stops giving power to spark plug the car will **** while driving.---------- So very first thing you get tested is spark plugs and ignition coil packs.If they are tested good, but looks very dirty/ worn out, that can also be the reason.----------- But if spark plugs and ignition coil tested ok and cleaned properly, but still same problem, then get fuel pressure tested.If fuel pressure is low, the fuel pump and fuel filter are the cause of problem.----------- ------------------ Also one more thing, " IS there check engine light coming ON dash" ? If yes, then get the car scanned at autozone service center.Its absolutely free to get car scanned at autozone.They do it for no charge.------- In scanning you will get error codes, as per error codes, it will point towards faulty part, causing this sputtering and jerking problem.----------------- But if there is no check engine light ion dash, then get the above mentioned possibilities checked.That will help.Thanks.Helpmech.

If you have spark at the coil then you have a good coil. You can't measure Ohm at a spark plug since it is alway open at the gap. But you can OHM measure a spark plug wire at both end. If you have nothing mean your wire is bad. You can swap one more wire to confirm a bad wire. If your wire is not bad then I recommend to replace both rotor and distributor cap. Good luck in locating the problem.

This sounds like your transmission is slipping. When it slips you will lose power when it catches back that's when you get the ****. Hope this helps.

No power when going up hill could be a plugged catalytic converter or fuel filter. A bad ignition control module will act up when the engine gets hot and not energize the coils so they can provide spark to the spark plugs. There could also be a bad coil. The ticking could be a bad coil or spark plug wire that is shorting and arcing. If you take a spray bottle with some water and lightly mist the coils and spark plug wires with the engine running in the dark (outside at night) you will see the arcing. Autozone will test your ignition control module and coils for free.

sounds like you have a problem with the spark the coil may be on its way out or there may be oil in the spark plug holls shorting out the spark.
your best bet is to pull the leads out 1 at a time and and look down and check for oil if there is oil there get a new rocker cover gasket.
if no oil refit plug leads loosely and start the car remove one lead at a time slowly and look at the spark cumming out the end off the lead is it blue? if so it is ok if it is yellow and dull you have a coil problem. also check that the spark is only comming out the end of the lead as it may be comming ou the side of the lead and shorting to earth,
you can do this by slowly moving the lead around the top of the sparkl plug holl and see were the spark is comming from

be carfull no to shock your self as it herts like hell

good luck
