The coil keep going out


You may want to check the spark plug, if the plug is really bad it can cause the coil pack to fail. Also try a higher end coil pack as well. If problem continues to exist then I would take it to a professional mechanic.

Engine oil in cyliders with spark plugs


it means that the rubber gasket and the rubber seals on the spark plugs got hard and allows oil going through to spark plugs.What you have to do? If you know how,remove the rocker cover and renew the gasket and the seals for the spark plugs and your problem stop to exist.

When car gets to operating temp it looses spark


Secondary Spark Test This spark tester looks just like a spark plug. Attach the clip to ground and crank the engine to check for spark. 91052p10.jpg

This spark tester has an adjustable air-gap for measuring spark strength and testing different voltage ignition systems. 91052p11.jpg

Attach the clip to ground then crank the engine to check for spark. 91052p12.jpg

This spark tester is the easiest to use. Just place it on a plug wire and the spark voltage is detected; the bulb on the top will flash with each pulse. 91052p10.jpg

NOTE: The best way to perform this procedure is to use a spark tester (available at most automotive parts stores). Three types of spark testers are commonly available:
  • The Neon Bulb type is connected to the spark plug wire and flashes with each ignition pulse.
  • The Air Gap type must be adjusted to the individual spark plug gap specified for the engine.
  • The last type of spark plug tester looks like a spark plug with a grounding clip on the side, but there is no side electrode for the spark to jump.
NOTE: The last two types of testers allow the user to not only detect the presence of spark, but also the intensity of the spark. Orange/yellow is weak, blue is strong.
  1. Disconnect a spark plug wire at the spark plug end.
  2. Connect the plug wire to the spark tester and ground the tester to an appropriate location on the engine or frame.
  3. Crank the engine and check for spark at the tester.
  4. If spark exists at the tester, the ignition system is functioning properly.
  5. If spark does not exist at the spark plug wire, perform a diagnostic test of the ignition system using individual component diagnosis procedures.

After changing my spark plugs my car is now spurtting...


did you properly gap the spark plugs?? Gap the plugs properly!! If the problem still exist, check all plug wires for looseness or breakage and replace all (recommended). These issues will cause your vehicle to misfire/sputter!!

CAR TURNS OFF WHEN RUNNING NO SPARK ON SPARK PLUG WIRES


First check to be sure that you have constant +12 volts to your ignition wire (red). Also be sure that there is +12 volts on the yellow wire when the key is in the start and run positions. If both of the above are true, then the problem likely exist in the ignition coil. Replace.

Number 2 spark plug


Are you sure it's the spark plug that's faulty or the ignition wire?? How old are plugs and wires?
If you don't know if it's your spark plug not firing or your ignition wire you could move spark plug to number 1 then check your code reader.
Or you could do an ohms continuity test on your number 2 ignition wire to verify that there is no break in the wire. Common problem to check for. If wires and plugs are old and high mileage maybe should change all including cap and rotor on distributor. Fresh wires plugs cap and rotor always improve mileage and performance.
Good luck, sorry can't help with tranny.
