Missing and here spark - 1993 Volkswagen Passat

check for the spark plug leads.inspect in the night under the hood if u start the engine and see the spark from leads.if u find spark leads good then check the distributor cap whether it is wet or moist inside?

check your spark plug wires. it sounds like cracked spark plug wire that is arcing. the best way to check this is at night , start engine and look for sparks around the plug wires.

DID YOU GAP SPARK PLUGS AT 0.060 FOR 3.1L ENGINE OR 0.045 FOR THE 3.4L ENGINE.DID YOU BUY AC R44LTSM SPARK PLUGS. DID YOU BUY AC DELCO SPARK PLUG WIRES.BECAUSE IF YOU BUY WRONG TYPE SPARK PLUGS AND WIRES CAR WILL MISFIRE.

Start with the simple things first. When was the last time you had a complete tune up? "Missing" could indicate bad spark plugs, bad spark plug wires, or bad cylinders. Change the plugs first, then go from there.

Question is very unclear.

HOWEVER:
We have had a discussion in reference to solving your problem.

Results to your answer as asked.

-Replace your missing engine, if your missing entire engine we recommend a long block (This will be an entire engine). To include replacement of the missing plugs wires and cap.

hope this tip helps.

No it does not have spark plug wire's, it only has ignition coil boots. Just replace spark plugs, if engine not running with a cylinder miss you'll be ok, if it is running with a cylinder miss you might want to check your ignition coil pack for spark.

could have cracked the porcelin on the spark plug

You can have car put on scope and it wll show any irregularities in the ignition system. It can also be dowithout any equipment. First, loosing ALL 8 spark plug wires, Now place the spark plug wires loosly back on, just secure enough to secure. You might need 2 people. Being the miss is more consistant in gear, APPLY THE EMERGENCY BRAKE , put trans into drive and raise rpm's till miss is obvious. Remove ONE plug wire at a time, TILL THERE IS NO DIFFERENCE IN MISS. Thats the cylinder missing. Start with the spark plug, inspect, work back to wires and cap. An EXTREME result will be NO COMPRESSION.

missing on occasion? you changed the plugs? was it missing before are after you changed the plugs? Missing is usually caused by a spark failing to jump across the spark plug gap.i would first look for a broken spark plug insulator. Secondly, bad spark plug wires ( if you re-used them the connector might have pulled off the wire internally) also look at the coil and distributor for cracks or other problems if the plugs and wires check out ok .

did u check spark plug, distributor cap and roter
