Title: Mkiv misfire very unusual
Post by: Mkiv+more1.8 on 20 June 2017, 21:12
My mkiv golf AGU keeps misfiring
The problem started about 2 months ago
I have replaced the following

Maf Sensor
Coolant temp sensor

When I scanned on vcds I got these problems

Coolant temp sensor
Maf sensor SIGNAL TOO weak
Lambda sensor

I replaced the maf and the rest of the codes went away I re-scanned and there were no problems all coils.are fine but i replaced the coolant temp sensor anyway
I don't have a clue what it could be

I have looked for vacuum leak and no results I haven't tested another ignition amp but I highly doubt that would be the problem any help would be great

The problem still consists
