2 weeks ago I got my spark plugs changed and ignition coils, wires, and alternator changed due to my car misfiring. So now it's doing some of the same things but worse. Before it would lag while driving then stop accelerating but the engine would still have power. But now it's doing more. If I turn I can't accelerate in the middle of the turn for a minute. If I stop it takes a minute before the car will accelerate. If I back up it will stop accelerating and take a minute before it starts back. If I'm driving it will stop accelerating while I'm driving and then start back. I car jerks when I put it in drive or reverse. The engine was replaced 6 months ago, headgaskets, new water pump, hoses are new, and the stuff I just got done 2 weeks ago

My car has 94522 miles.
My car has an automatic transmission.
