P304 code. bucks/misfires at 4k rpm
Im driving a 02 3.0L V6. 155k miles.
new parts listed...
valves and heads
been driving it for about 2 months after the valve job and truck runs much better. this bucking and misfire under load comes and goes, has been like this well before the new valves. however it just now gave the the check engine light that says #4 cyl misfire.
