Another misfire thread!
I was previously on Unitronic Stage 2 (downpipe and intercooler upgrades only) and never had an EPC light.
Just installed a basically brand new IS20 turbo and flashed to the Unitronic Stage 2 IS20 file, and now got an EPC light and some codes under boost:
Cyl 1 Misfire Detected P030100 (intermittent)
Cyl 3 Misfire Detected P030300 (Static)
Figured it might be bad plugs after 44,000 km (27,000 miles).
Bought some new NGK PLFER7A8EG plugs in, gapped to .025.
Seems to run better overall, did some pulls and it seemed okay. But then went to do a highway pull in 3rd and now have a code for Cyl 4 Misfire P030400 (intermittent).
Before spending money to try new Coils, does anyone have any suggestions as to what could be causing this after an IS20 install and tune?
