Was the harness and ECU swapped when the 1.8L was installed or does it still have the stock computer? If the harness and computer weren't changed, you'll have to use the 1.6L VAF.
He told me I needed to get the 1.8, so I assume he changed ECUs. s*** I forgot to ask. I can't leave the house because someone on my block blew their house up (seriously) so I have time to call him.
