Question

I used my Diablo and put the 91 octane code in my 2005 Chrysler 5.7 300 and it started missing and won't rev past 4000 on the tach. When restoring to the stock code it is still missing and giving me the P1411. Will it hurt to drive it this way?

Answer 1

HI there

This code means it's not making the switch. It is basically a misfire on cylinder #1 and should not be driven this way. This can lead to a damaged catalytic converter.
