1999.5 Jetta Bunch of codes
Hi guys,
I have had a CEL on my Jetta for a while. I have noticed that if runs rough for the first 10 minutes after it rains.
I check the codes at my brothers house and got a tonne of codes.
P1128, PO172, PO440, PO134, PO300. I was surprised at how many.
It is a 2.0 Jetta AEG. I was thinking of changing the coil pack, plugs and wires to start. Any ideas?
