Car won't accelerate after a bend in the road.

Asked by Dec 12, 2015 at 06:28 PM about the 2007 Pontiac Grand Prix Base

Question type: Maintenance & Repair

So I'm going 45 to 50 and their is a bend in the
road that forces you to go down to 30mph. After
the bend when you try to go back to 45 it won't
do either wait a few secounds or take you're foot
off and try again.

There really is nothing to go on so I would say do a tuneup and have the catalytic converter checked to make sure it is not plugged up.

Sounds like the transmission isn't downshifting. HTH. -Jim
