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.

Hello i have a GTI its a 2.0L manual transmission, i have been having problem after problem thus far. Current engine codes PO422, PO300,PO304,PO303,PO302. I do not have a code list to see what these are...


I think that PO422 is the Cat Converter, it may be bad or may be just the O2 sensor.
The PO300, 302, 303, 304 code have to do with the ignition coils or wires. (302, 303, 304 means there are ignition /firing problems in cylinders 2, 3and 4). If your lucky just the wire and new spark plugs.
Google "engine codes Jetta" for more on web. Good luck.

MISFIRE ON CYLINDER 4 AND 6 WITH AN ENGINE LIGHT ON


Check the coil packs on the plug if equipped with that type, or the coil packs at the end of the spark plug wires, if so equipped.

Also, check that the fuel injectors are firing on all 8 cylinders.

Definitely, check out what other codes are stored in the computer besides a missing condition.

I have a 1999 Expedition that had a miss on a cylinder, and it turned out to be a bad coil pack. You have 2 cylinders missing, so I would check each cylinder for good spark, or replace the coil packs as necessary to see if that resolves the problem.

Good luck on this repair.

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

1999 grand prix gt 3.8v 6 error codes 300 and 302


The PO300 code is random/multiple cylinder misfire detected. Sinsc you have the code PO302, that means that cylinder 2 is the one misfiring, usually a bad coil pack, or spark plug.

I have a 1999 VW Passat 1.8l turbo. It has codes P0300 and others


They may not be firing. I would check spark from coils. You may have a bad coil pack. Do check for any vacuum lines. You can go to autzone.com and register for full free online repair manual
