You are going to need to borrow some tools or go out and buy some to run some quick tests. If the misfire is in cylinder 1 ONLY, the easiest thing to do is to check spark, (spark plug tester).

  1. Put the spark tester into the plug wire and have someone crank it over. Make sure the plug tester is grounded to the block or some metal bracket, otherwise you could damage your coil. IF you don't have spark it could be due to a bad ignition coil. If you have spark at the wire and not the plug then you have a bad plug. IF you have spark coming from the coil wire but not the spark plug wire then you have a bad spark plug wire.
  2. If you see there is spark, the next step is to pull the plug out and test the plug itself. Plug the spark plug into the wire you just tested and pull the fuse (or relay) for the ignition or fuel pump. This will keep the car from starting, but will still allow you to see if the plug is firing.
  3. Also check the plug to see what condition it is in. Has the car been serviced recently, check all of the things that have had serviced.
  4. If you have spark the next thing is compression test. Screw in the compression tester to the spark plug hole in the head. Crank over the engine 3 times. Read the specification and look it up to see what the specification should be. Anything between 115-150 should be acceptable. IF you have any doubts test other cylinders to see what they are running.
  5. The last thing is to check for fuel, that is if you have found spark and compression. Locate the fuel injection port, on some VW models they are not used so consult a service guide if you're not sure.

    On VW's a faulty injector or faulty fuel delivery will cause a cylinder misfire. A simple low fuel level in your tank while turning can cause the fuel to shift away from the fuel pump and cause a misfire. Hook up a VAG 1552 or equivalent scan tool to properly find out where your problem is located using the DTC code that might be stored in the ecu. I wouldn't do the typical remove wire and see if spark is present, this can eventually fry your expensive ecu. It's a VW and not an American car.

This could be a bad cam sensor that hasnt gone yet. It would explain why you are running to lean.

MY TRUCK IS RUNNING ROUGH AND HESITATING WHEN APPLYING GAS WHATS THE PROBLEM ITS A 1998 FORD EXPEDITION


With a scanner connected to the car it may have codes to help you find the correct problem. like P0300 is readom cylinder missfire ( this means that many cyclinders miss and can be a vacume leak to low fuel pressure to EGR valve hanging open) P0301 -P0308 can be any number of these cyclinders misfiring as the cyclinders are numbered( The boots on the coils going over the spark plugs fail or get oil or water or even antifreeze in them and they miss. To pull the coils you need to pull the injector rail and if your not a regulr mechainc you sould hire this work done as the things you can break the a regular mechanic won't, May save you more than what the pro is going to charge.

98 passat # 2 missfire help


If your getting a P0302 ( cylinder #2 misfire detected), the first thing to check is the spark plug. If it's new then the next thing to check is the plug wire. If it has individual coils, then swap it out with another one and see if the misfire moves too. If so then the coil is faulty.

2000 lincoln navigator unable to bleed up fuel


I think I would try the easiest thing to fix and then see how much straightened out. The fuel tank vacuum will probably be a gas cap not on tight or defective or a gas vapor line has a hole in it. You may need a smoker to find that leak if the gascap is okay,

Bank 1 should have cylinders 1,2,3,4. Since 3 cylinders that are in the same bank are misfiring it must be lack of fuel or bad spark. The tester said that bank was lean. If the plugs were not firing it would be rich with unburned fuel. The tester also indicated the other fuel tank vacuum bleed problem.

You might try the power connector for the Bank 1 injectors or check the injector wiring for #2,3,and 4 to see if they are getting power.

Remember to clear the diagnostic meter to see if the trouble codes return. Would be interested in the outcome.

Engine missfire


Check your spark plugs and wires. Ensure they are all correct coming off of the distributor cap. You may wanna even change them (plugs, wires, and cap) just to make sure they are all in good working condition and you put them all on in the correct placement/order.
