You would use the DLC (Data Link Connector) plug.
Sounds like an engine misfire. Can be bad spark plug, plug wire, fuel injector, or bad coil on plug.
Bad spark plug?Bad plug wire?Bad valve?*Bad piston?* Do a compression check to check engine internal condition
Check Spark plugs Check plug wires Do a compression test
Remove the spark plug wire from the spark plug. Use some heavy gloves or a set of insulated pliers to hold the spark plug wire about 1/4-inch from the engine block (ground) and crank the engine - you should see a spark jump from the wire to the engine ground. For a better check, use another spark plug and put it on the spark plug wire and use it as a "jumper" from the wire to the engine ground.
Yes
Probably a spark plug is fouled up.Also check plug wires if you have an older model.
Usually if im working on an engine that a cylinder is missing. I first check to see if there is spark to that plug. if thers no spark, then its either a plug wire or distributer cap problem. then check the plug, if you got the plug sparking, you may have engine trouble
Check the Vehicle Emissions Control Information ( VECI ) decal in the front of your engine compartment ( it will show the type of spark plug to use and the spark plug gap )
underneath the cup holder
I would check the plug wires and the exhaust system.
Check the bottom of the engine oil pan.
