Default Engine Misfire
Hi everyone,
I need a little help trying to figure out an issue i'm having with my 2017 Raptor. Its misfiring in cylinder 1 & 3.
the codes I'm getting are:
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 misfire Detected
P0201 Injector Circuit/open Cylinder 1
P0203 Injector Circuit/open Cylinder 3

Im guessing the vehicle is detecting a misfire so it's shutting open the injector pulse. I have replaced the spark plugs with no luck. Ive also swapped the coils around. both Cylinders are getting good spark.
the vehicles only done 200 miles.
I live in Australia so I cant go to my Ford dealership and ask them to look on it so I'm on my own over here.

Any help would be much appreciated.

Where did you get it from and was it brand new? or did you end up with a car that may have been flooded?

i got the vehicle from a Ford Dealer in Canada. i have 9 of the same vehicle and 2 of them have this exact same issue.
I'm stumped on what to do next. I'm going to take the GAS out of it this morning and see if that contaminated

The funny thing is i started the other one this morning that has the same issue and its now running perfectly....

what octane fuel are you running?
Remember the Raptor is higher compression than the gen2 ecoboost and requires 93 octane (US/Canadian fuel is on the Ron+Mon/2 formula, not straight RON or MON).

No less than 87 octane is required, but Premium fuel is recommended.

Oh alright I see. I thought they were for your own personal use. Since you sell Raptors, I am currently looking into purchasing a 2011 Raptor with 37K miles. Is there anything you would recommend to look at before purchase?

Rodents chewed the injector harness? I've seen that happen many times. Sometimes they chew partially thru leaving a few strands that may not carry the load at all times.
