Random misfire

[GA2Dr]

Hi all:

Was driving yesterday, got on it (about 80% throttle) and not long after hitting peak boost I saw the check engine light flashing. Immediately got out of the throttle. Check engine light continued to flash but never went solid and no warnings or other messages popped up. I did not notice any rough running, hesitation, etc.

When I got to the next traffic light I shut the Bronco off and immediately restarted it. No check engine light and it ran fine rest of the drive. Drove fine today and has not happened again even with going WOT a few times to test. Put Forscan on tonight and zero codes.

I have been running my current setup (mods) for at least eight months with no recent changes of any kind. In searching on the forum I understand a blinking check engine light means a misfire. Given the above should I just chalk this up to a random misfire and move on with my life?

Thanks in advance for your thoughts.

You made mods and experienced a malfunction, but haven't told us what mods you did.

Correct

And?

We had a pretty significant misfire issue on one of our broncos. Dropped the gap down to .029 if I remember correctly. At first we still had occasional issues but now that you’re bringing it up it’s been quite some time.

"A blinking check engine light in a Ford Bronco indicates a severe engine misfire. Unburned fuel is dumping into the exhaust system, which can cause extreme temperatures and quickly melt or destroy your catalytic converter. This requires immediate attention"
