Well, in the last 7 years I have been very good about cleaning out my filters about once a month or so just as caution. As well as having the injectors cleaned at least once a year. Always warning people to keep an eye on fuel pressure, and air fuel ratio once they swap to E85.
My car has been flawless as usual, same plugs, no tune changes.
Then I got gas a week ago, and 1 day later got the fuel pressure warning.....
Here is what I found today when I pulled the filter.
The dreaded "E85 mystery goo balls"
Now I know there are allllllll sorts of theories on internal vs. external pumps, and heat in fuel vs running coolers, and additives etc. However I can run months without an issue what so ever, then magically after one fill up get this. (without any change to my set up) So, who knows what really causes it...all I know is that if you run E85, make sure to keep your eye on that AFR, and FUEL pressure.
PS: So I run a $4000 ecu on my car, that I have programed in many safety functions, to shut down the car if issues arise that could hurt the motor. (Such as AFR ratio per psi, fuel pressure monitor, etc) All of these functions can set codes, flash a light, or shut the motor down if something is bad enough.... (aka, fuel pressure dropping) So no motor damage happened, just a warning, and some down time to clean everything.
