Silverado misfires
Have a 2004 Silverado 4.8. After truck
warms up and I shut it off when I restart it
My engine light flashes and I get a p0300
code. If I drive it straight to work then after
work straight home it's fine but if I stop
somewhere when I restart it that's when it
happens. It runs rough the rpms don't go
above 5 when I get on it and it idles really
low.
