2010 impala stall/idle problem

Engine revs erratically on idle.
Engine stops running when I slow down.
Weak acceleration

Any idea of what the problem might be?
Thanks.

Any check engine lite? Lottsa possibilities, without more definitive info anything is a guess. Look for a major vacuum leak for starters.

Hi Max wedge,

Yes, the check engine light turned on and popped the code P0443 which is the evac purge solenoid. Tomorrow I'll change it, hopefully that solves the problem.

Thanks for the reply

Before just changing a part which may be intact, check the connector, the PCM fuse(s), and meter the resistance of the solenoid.

Agreed Blue, based on the op's symptoms, seems that would not have much affect on his condition, even if the hose was off.
