Hi, when you start the car does it idle
ok before driving? It could be your
throttle position sensor that could be
one thing I'm not sure it's hard to
know what's wrong unless I had
more information like knowing how
many miles are on the car & has it
been tuned up lately has anybody
worked on it lately? All I can think of
is a throttle position sensor cause I
had to replace mine and it acted
funny with the idle it might be trying
to screw things up as far as driving
the vehicle I'm not sure could be the
spark plugs too hard to tell hope this
helps?
