"EMI" fuse blowing
Back in October, my "EMI" fuse (15 amp, powers transmission shift solenoids & O2 sensor heaters) blew while driving on highway (car dropped from 4th to 3rd unexpectedly, SES lit up).
Got home, checked for shorts on O2 sensor wiring, none found. Replaced with new 15 amp fuse, problem solved.
Today, while at full throttle, car shifted to 2nd way early, SES lit up.
Checked fuse, blown again. I've replaced it but haven't driven yet.
Anyone else have problems with this fuse blowing, what could be root cause, assuming wiring is not chafed/shorted?
Remember, when not sure what to do, hit the throttle.
It may not end well, but at least it'll end the suspense.
