Title: Emmisons Problem/Running Rich
Post by: Yorkshire_83 on 16 April 2014, 13:08

Hi all

New to here, but need some advice.

Got a MK4 Golf AQY (Gti 2.0)

I've had problems with emmisions recently:

MOT failed, they adjusted the 02 sensor and it fixed it.
Engine managment light came on 2 month ago, i changed the sparks and leads, fixed it (after code read cylinder 3 misfire).

Now engine light is on again and it stinks of un burned petrol. Garage can't look at it until next thurs, but need the car this weekend, before i change the coil pack or put a new 02 sensor on, anyone have any tips as I know these mk4 golf's are renowned for these issues.

Many thanks if anyone has any suggestions.

You need to scan it and see if that pinpoints anything
