It will have an effect on your performance, as the engine will retard the
ignition timing to combat knocking, resulting in less power. It won't
actually hurt the engine - that's the whole purpose behind knock sensors.
Yep - all of the x.7L's have knock sensors (so does the Viper's 8.3L). Two
of 'em, bolted to each side of the engine block.
You're correct about the 3.9/5.2/5.9 (and the 8.0L as well, contrary to what
a former member of this group espoused) - no knock sensors there.
tha e truc was designed to run on higher octane fuel and if you don't
it could set a check engine lite and the pinging does do damage over
time the louder it is the worse it becomes knock sensors are not
desinged to counter that effect
i have a rt and a mopar hipo pcm and also i'm suppose to have premium
fuel but i use a octane booster that is cheaper than the premium gas
and have good results
