Chuck..if that's 1st time you've used bio. maybe its like
VFT says. Ever read the bio fuel forum here.
At very least..drain HFCM & see what fuel looks like. Inspect both FF..if cruded up change um. If u disconnect the batts. the CEL/SES will go off & codes get erased as u probably know. You can try a DIY OR If u take in..CEL needs to be on. PT warr.(ded) may cover? Good luck.
FWIW..So far Only B5. B20 not FMC approved.
