Title: Bad misfire on agu
Post by: yickergti on 30 September 2011, 17:30
Hi all,my car has developed a bad misfire this morning and sounds like a small subaru. I drive the car home 10 mile fine from work with no problems,started to reverse it into the drive and it started to chug. I checked the coil packs 1 at a time and when i removed number 3 it made no difference so i though great,sussed it,easy fix,went and got a coil pack but its still doing it  :cry: Would plugs be the next thing to change? The car is a 1999 agu 1.8t

Any help would be appreciated  :smiley:

Check your plugs yes or change plug 3 for plug 4 and see if your misfire moves  :wink:

Do you have access to vagcom?

Have you swapped the spark plug for a know good one and this is your conclusion?

The neighbor just said its the coil pack thats not sparking. Tested by putting a spare plug into the coil and running the engine
