Recently acquired a 2008 GTI SE 155. Plugs were fouled when I bought it, so I installed new NGK's and fired it right up. Engine produced smoke and would not reach 5000 rpm. Pulled it home, pulled the plugs and they were black and wet after about 15 minutes of operation. Pulled the fuel rail to take a look at injectors and all 3 seem to be dumping excessive fuel.
I suspect a bad sensor (TPS, MATS or IACV), but don't have a way to read engine codes (CANDOO order placed, but won't be delivered for a week). I would like to proceed with some troubleshooting, but I realize that may be difficult until I have the reader.
Has anyone seen this symptom? Could it be related to the fuel pump or regulator?
Anything obvious that I could check? I would like to get a headstart on the parts, because once I have a diagnosis, I will most likely have a week's wait to order parts.
