Check the wiring to the injector as there may be a fault/ dirty terminal/ water etc causing the problem

Dear Customer,

1
check your sensors 1st,all sensors must be good

2
if all sensors are working good than check your engine firing sequence,some times happens when sequence was wrong,

3
check your exhaust and carborator tuning pin that creates the batter combination for firing in bore for batter performance & less emitions ,so check is it ok or not than go to your nearest service center that havad certified mechanics,

till you read this you had solve this problem definatly,

SOURCE: MISFIRING ON CYLINDER 1 VW POLO 1.4 3CYLINDER

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

SOURCE: Removing VW polo 2005 battery?

Removing a battery from a Beetle is a bit complex and tricky. I just changed the battery in a 2003 2.0 Beetle. However, the process is very similar in a TDI Beetle. You will need more than your standard generic tool set in order to complete this task. Your tool list needs to consist of a pair of pliers (prefer locking type), a # 20 TORX head screwdriver (You will also need this if you ever plan on changing the Beetle's internal dash pollen filter for the A/C. ), a 10 mm and 13 mm sockets, a long extension and a wobble or universal to allow flexibility in tight spaces, an allen socket for removing the power steering reservoir, and a small adjustable wrench or a 10mm to remove the battery cables. If you are changing the battery you might as well buy a new Air filter since you will need to remove the air box in order to replace the battery. If you do change the air filter you will need a phillips head screwdriver.

1. Pop the hood.
2. Remove the two 10 mm bolts that hold down the air filter box.
3. Undo the clamp that holds the large tubing to the air box using your pliers. Move the tubing away from the box.
4. Unclip hose attached to the back of the air box near the large hose (under it).
5. remove the small breather hose from the air box.
6. Pull air box up and out.
7. Remove snap on cover from top of battery.
8. Remove small snap on wiring cover from back of the battery covering.
9. Unbolt power steering reservoir (next to battery case).

10. Disconnect the battery cables. Positive side first.
11. Remove the 13 mm bolt at the base of the battery along with the hold down clamp.
12. Pull the top wiring away from the battery case and then slide the battery towards the engine.
13. Remove the plastic battery case.
14. Remove the battery

Hello, I have a Honda Civic of year 1999. A trouble code 74 has been diagnosed. It is a misfire on the 4th cylinder. Can you please tell me how to fix same.


the misfire on a particular cylinder can be from several reasons
1--- mechanical--burnt valves , loose valve seat insert , hydraulic tappet holding valve open===run a compression test to eliminate mechanical faults
2-- electronic
faulty injector, faulty injector tip( blocked) faulty injector wiring, plug, ht lead --ecm
cracked insulation in distributor cap or coil housing
moving a faulty injector to another position will move the miss or simply replace it with a known good unit

Rav 4 turbo diesel 1 2 3 cylinders are all working when you take off connector when running no 4 nothing happens


There is a fault with no 4 cylinder. Could be: Faulty new injector, faulty ECM not firing injector, low compression on that cylinder. I'm assuming its a newer common rail model - I suggest getting the injector swapped to another cylinder and see if the problem moves. IE: swap no 2 and 4 injectors - if the problem moves to no 2 then the injector will need to be replaced.

My 1996 Taurus when I press the gas pedal when cold it sputters and lacks power. When it warms up it runs great.


Possible causes - Faulty spark plug 5
- Clogged or faulty fuel injector 5
- Faulty ignition coil 5
- Fuel injector 5 harness is open or shorted
- Fuel injector 5 circuit poor electrical connection
- Ignition coil 5 harness is open or shorted
- Ignition coil 5 circuit poor electrical connection
- Insufficient cylinder 5 compression
- Incorrect fuel pressure
- Intake air leak

The P0305 code means that the cylinder 5 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 5. If the problem persist more tests needs to be done to diagnose problem, see "Possible Causes



When is the code detected? Engine Cylinder 5 is Misfiring.


When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

1999 VW Passat 1.8 turbo Code #3 cylinder misfire. Replaced coil and all plugs, still have misfire...???


Coils and plugs are not the only things that can cause misfires. Misfires can be caused by vacuum leaks, low compression, faulty fuel injectors, clogged EGR ports (on vehicles with individual ports for each cylinder), blown head gaskets, burned valves...you can spend a LOT of money on parts by just going in and replacing things without diagnosing WHY the cylinder is misfiring.

Airbag light remains on after changing fuse of rear wiper.VW POLO


This is a common occurance in vw's.
In order to turn off the airbag light you need to have a scan tool hooked up to your car because the airbag detected a fault of some sort, or it could be a faulty component in the airbag system itself.
