my trucks running bad
My truck has a 3.4 5vz-fe engine its acting
up it takes a while for it to start, it idles
rough, and then when I start going its starts
jumping, spiting and backfires. Ive changed
the mass air flow sensor, ive cleaned the
throttle body, ive changed the fuel filter, and
change the spark plugs. But is still doing it.
The check engine light is on and its says
something about the air and fuel ratio. If yall
can please help!
