Hesitation after tune up 2010 Mazda CX9

2010 mazda cx9

I got a Tune Up with new plugs, wires, etc. When I drove the vehicle it began to hesitate when you pickup speed, and it wasn’t doing this before needed tuneup, the check engine light doesn’t come on so the plugs are firing so what could be the problem.

Could be a vacuum leak or a hose slightly left loose. Sometimes double checking the work is the best first place to look.
