Question about 2001 Volkswagen Passat

Misfire in cylinder 3

I have an intermittant misfire in cylinder 3(VW 2001 passat 1.6 petrol). The car can drive fine for a day and then begin misfiring. The coil packs have been changed the plugs and the injector have been changed. A trouble code of the throttle position sensor came up and I changed it. The car drove fine for 2 months and is misfiring again. Now I have a mass airflow sensor diagnostic code from time to time. Can a mass airflow sensor cause a misfire and if not what else could cause the misfire besides the wiring from the ecu and the ecu itself.

NO to the MAF Sensor Question, and Spark Plug Wires Or BOOT Will Cause Missfire. As For Mass Air Flow Sensor Easy Check is to Dissconnect it While Engine is Running And If ENGINE SMOOTHES OUT The Sensor is Bad

How to fix diagnostic code for 1999 vw passat po304 po305 po306


Hi. You have misfires on cylinders 4, 5 and 6. If there are no faults on cylinder 1, 2 and 3 then I would check the power to the left bank injectors. Also check spark plugs and ht leads. If there are running issues then this should be an easy fix. If the faults are very intermitant then it can be a bit tricky to isolate.

2001 Passat 1.8 Turbo engine sputtering and hesitating


My car was doing this and I had to get all new coil packs... Mine were replaced under recall at the dealership at no cost. If you take each code and google it, or even check a VW forum, I'm sure the members there can provide a lot more thorough information...... I have a 2001.5 Passat myself and when one thing goes out they all follow suit. I will help with some research for you and post back...... But I'd check the coil packs that sit atop the spark plugs.

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.

I have a p0303 trouble code on my 1999 Passat. Missfire on #3 cylinder. Coil is ok, I'm lost.


coil packs very prone to failing... check compression for good readings (at least 100 - 120psi) if okay try new spark plug as these can fail under load and its the cheapest part to replace to eliminate. if misfire still present swap cylinder 3 coil with cylinder 1 coil and see if fault code moves to cylinder 1. hope this advice helps

There may be no check engine light but that doesn't mean there isn't a code in the ECU. Especially with a misfire. I'd have the codes scanned and see what you got. The cannister issue isn't going to give you a misfire it will give you stalling and rough idle.
Lets see what ECU is saying. You can go to Autozone if you don't have a scanner they will scan it for free. If scanning turns out negative than have a cylinder leakage test done. This way we can determine which cylinder has the problem and what the problem is.

2004 Audi A4 misfire


it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

1999 Town Car began running very rough - suddenly.


When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.
