^^^ As He said, I was chasing a misfire this week and was thinking something bad was happening or I damaged something.
PR's where a breeze to take on and off.
Without the PR coils I would have been thinking it must be electrical or something to do with plugs or mechanical damage.
Ended up being the local fuel company being cheapskates most likely due to covid-19 to save money because of the low fuel prices thus lowering the fuel quality.
Before I could run 24 - 26psi with no timing corrections, now I cant even run 22 psi without misfiring.
I was running around on e20 but had to raise it to e50 to subdue the misfires.
The whole point to the story is, no matter what you throw at the PR's it will never be them but something else if you develop an issue, its set and forget.
