What have you done to your mk4 (golf/bora) today?

[Manaz]

Feels like it's pulling a bit harder. Nothing huge but yeah, there's a little difference.

You may want to look at your MAF if you had significant oil buildup in your intercooler - you may find that the hot wire is dirty (oily), which would throw out readings - a cleaned (carefully!) or new MAF may help.

Ahh ok thanks for that. Do you know if the new one in my 2 litre is a straight swap?

[Manaz]

Fairly simply swap - unbolt it from airbox, unbolt it from intake manifold, unclip wires, replace.

You clean them very carefully with carby cleaner I believe. Have to be careful because the hot wire is delicate.

Cheers. Just had a look and it's squeaky clean.
