My 1994 Nissan Altima started shaking really bad. I gave it a basic tune up. I replaced the spark plugs, spark plug wires, distributor cap and rotor and gave it an oil change. I left the car running and checked to see if there was a misfire. I pulled up each spark plug wire one by one and when I pulled them up 3 out of 4 of them wanted to "die out" which is suppose to happen. So whats going on with the one that didn't want to "die out". Aamco wanted to charge me to much to just check to see what the problem was.

Really need more info here. Does the engine turn over? If so check all your connections again. Also check plug and coil wires and distributor cap. If engine won't turn over it's probably the battery.

check timing and fuel delivery.

check fuel filter,or fuel injectors, fuel pressure regulator.Also check fuel filler cap.Check exhaust system for plugged catalytic converter,muffler,bent exhaust pipes,etc.

did you change the distributor or just the cap?

1. Ignition Switch: Improperly Connected or Faulty Ignition Switch.
2. Battery: Battery Discharged or Faulty or Coroded, Broken, Shorted or Poorly Connected Battery Cable.
3. Solenoid Switch: Starter Solenoid Switch Faulty.
4. Starter Starter Motor Faulty.
5. Wireset: Worn or Damaged Spark Plug Wires.
6. Coil -Ignition-: Faulty Ignition Coil.
7. Distributor Cap: Loose, Cracked or Worn Distributor Cap.
8. Spark Plug: Incorrectly Gapped or Fouled Spark Plug(s).
9. Distributor Cap and Rotor Kit: Loose, Cracked or Worn Distributor Cap.
10. Carburetor: Worn, Faulty or Damaged Carburetor.
11. Fuel Pump Faulty Fuel Pump.

If you've got spark from the coil but not at the spark plugs, it can only be 1 of 3 things.

• Bad spark plugs or plugs not gapped properly.
• Bad spark plug wires.
• Bad distributor cap and rotor. This is pretty easy to check. Open up the cap and look at the points on the underside of the cap and also the point on the rotor. If they look corroded or worn, then you should replace them.

Good Luck!

Spark plugs, spark plug wires, distributor cap, and distributor rotor. If you replace all of these you would be doing what is called a major tune-up.

A regular tune-up would be just replacing the spark plugs.

You can check the integrity of the plug wires and distributor cap by spraying them with water while the engine is running. If the engine runs ruff, stall, or you see spark arcing from either the wires or the distributor cap than they will need to be replaced.

The distributor rotor always gets replaced when you replace the distributor cap.

You can also spray the coil with soapy water to see if it is leaking as well.

Replace the spark plugs, spark plug wires, distributor cap, and rotor. Next, check the idle air control valve and replace it if found faulty. If it still shakes, have the timing checked out

All you really need is a good set of spark plugs, this car has coil packs so no plug wires distributor caps etc.....Just remove the coil packs and install your plugs and your done. Good luck.
