Q: jolting bad and stalling - 2009 Kia Sedona

asked by on September 02, 2016

I just changed the spark plugs yesterday and today trying to leave for work when I started up the vehicle i would jolt really bad and eventually shut down/stall. After 10 minutes I finally got it on the road but it was still jolting. When I would slow down it would stall, then at every stop sign it would take me a few minutes to get it going again, after stalling over and over.

My car has 142000 miles.
My car has an automatic transmission.
