Tune-up info, How can you check to see if you have the spark plug wires on correctly? The engine has coil-paks and I've never worked with these before and it's running ruogh and I think I have some wires mixed up. Carl

What parts would i need to do a tune up on 2005 mitsubishi endeaver


For a tune up with most newer cars all you need is spark plugs, spark wires, and boots if you have coil packs but that should come with the wire bundle. If you have a Distributor system. Then you need a distributor cap and button. With the spark plugs and wires. If you never did a tune up before. Replace the wires one at a time matching the wires in length. This makes sure that the firing order is correct. Check your pcv valve, and air filter.

Are plug wires connected in the right firing order to the plugs? Also are the spark plugs gap correct? Was vehicle running rough before tune up or only after?

Engine problems


Hi there:
When was the last time the engine was full tuned up? This sounds like a classic ignition misfire! They usually go bad under a load like under acceleration, but can be noticeable at any time.


It is very important to have your engine equipped with good tune up parts or you may be causing damage to other components of you car like the catalytic converter which can be expensive.


Possible causes:

Ignition misfire causes by any bad tune up part and or ignition coil or coils.
Bad spark plugs, spark plug wires and cap and rotor (if equipped)
Wrong tune up parts spark plug, wires etc...


The quickest way to check the ignition components, is by looking closely for leaking secondary voltage. Visual look at all the tune up parts to see if you can see any sparks coming from any of the wires or coil (or coils) when the vehicle is running. If not, you can put your hand on the coil/coils and wires when the engine is running and see if you feel any small voltage leaking form the tune up parts.

It will leak secondary ignition voltage from the tune up parts caused by high resistance from carbon tracking if they are bad. This is very common if the tune up parts are not changed regularly!


If any is found, the tune up parts are simply bad and will need to be replaced! If none is found than you can spray a mist of water on the tune up parts when the engine is running and see if that causes the engine to stumble or run rough at all. Again, if it does, the tune up parts are bad and will need to be replaced.



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

My husband did a tune up on my car yesterday and now it wont start it will turn over like it wants to start but it wont he said that its miss firing we have bought 3 new coil packs and still will not start...


If your car is miss firing and your husband changed the coil packs,the wires leading from coil packs to sparkplugs must have got crossed.This will change car timing which will result in the car miss firing.He needs to go over wiring and correct problem for car to run right.You can go online to autozone.com and type in Info about car to get the correct wiring layout.Your problem isnt the new plugs n wires.Its the wiring layout.

Service engine soon light on; diagnostic code states: cylinder 7, Misfire


you need to have your engine tuned up, unless it's been done recently. misfire means it's not getting fire or fuel to #7 plug. you may have a plug wire bad or a bad spark plug on #7 if you go to effort of sending it to garage just to replace one plug or wire,you'll pay labor for whole tune up. wires,plugs, and maybe a bad coil pack. suggest you have tuned up with new plugs and wires. also while they are there, have them check fire to #7 plug on coil first before you do a complete tune up. thank you for choosing fixya.com

Does the car have spark plug wires? i went to purchase some wires but the clerk said my car takes coil packs.. so do that mean i dont need wires for the spark plug tune-up??


So you want to tune it up , but someone has to tell you it has no wires? Have you looked at the engine at all? why do you want to do a tune up? The coils are very problem prone, and you need to use care in replacing the spark plugs, use only Auto-lite or Motorcraft platinum spark plugs, and use a silicone grease in the boots. After you remove the coil, blow compressed air down the tube an dblow out any dirt, before removing the spark plug. Wires are/were never an item for a tune up, unless they were bad. Replace the fuel filter.
