no engine told at all.
308 really means, this.
#8 combustion pressure (HP) power is weak, or
weak combustion.
caused by many things not just spark 3 things ASE otto cycle gas engines.! (basics)
1: bad engine, bad valves and compression test on #8 fails
2: spark bad #8 spark plug, wire set HV or COP bad. to 8 or cop boots bad on #8 (boots HV carbon tracked or useless)
3: injector bad. leaking or 1/2 clogged or even dead.
in that order, other odd cause but real.
intake runner gasket to #8 is sucking air, aka bad intake gaske.
some cars injector 8 has a bad seal ring sucking air.
bad head gasket but near #8 is worse .
warped head #8 worse here. and makes gasket fail overheated engine top cause.
keep in mind all we know is #8 is weak not why, only tests using real tools finds it.
I do a compression test on #8 and below 150psi is no good WOT.
swap injectors 7 <:>8
do RAD leak down test find coolant leaks not discovered yet.
check scan tool PID LTFT on both banks. SAME,
check 02 , S1B1 and S1B2, FOR CLOSED LOOP STATUS HOT IDLE
MAKE SURE HOT ENGINE PID ECT IS 180F SCANNED.
