2003 chevy impala lacks power and hesitates during acceleration. no engine lights or codes...any ideas? thanks
seems to hesitate about 1/3 pedal then after 3/4 pedal picks up hard but still not full power and doesn't seem to shift right due to no power.
Tune up spark plugs and wires check Trans fluid if that doesn't work u might need a new timing chain
like said in the above post. a tune up is recommended, the the spark plugs and wires replaced check your fluids, make sure your filter is good or replace it , inspect the throttle body as well could be an issue with a cable maybe something interfering or a throttle position sensor could be it as well. sounds like it could be a transmission issue, check your fluids and i also recommend the lucas gear slip fix additive for the transmission fluid. hope this helps you resolve your issue.
