Finished installing Vishnu stage I last night on MY04 wagon, and it would appear I have some knocking going on. Here is what got put in:
uppipe
downpipe
exhaust
pulley
Vishnu ECU programmed for stage I has been installed and running in 'valet' mode for a while with no knocks with everything stock. After installing the above, knocking seems to be present in both modes.....
installed the mechanical CEL fix for the rear O2, and the resistor for the EGT.
No exhaust leaks, no CELS, nothing obvious. idles fine, etc.
Suggestions?!? What should i be looking at?
