2007 Hummer h3
I have a 2007 Hummer h3. I have had a miss and
replaced the coils plugs and injectors. And check
engine light went off. After three days the light
came back on saying fuel cap or running lean.
While driving rite under 2000 rpm sometimes it
has a stutter. Give it gas and it stops. Also
sometimes after getting gas it seems hard to start.
Give it gas and it cranks but have to keep the rpms
up or it will die. After going it's fine. Any clue to
what is causing this.
clean throttle body and airflow sensor
