Engine Performance problem
2002 Jeep Grand Cherokee 6 cyl Four Wheel Drive Automatic 56400 miles

Problem started after having been into the shop where they replaced spark plugs, and flushed transmission.
When I am at a stop/ standstill.(Usually my first trip out driving the Jeep and driven a few miles) I press on the gas pedal to start driving again and it doesn't accelerate. It hesitates. And the acceleration from 20-30mph is very slow. Doesn't always happen but more than not on the first trip out. Once I am past 30mph it acts normal, no hesitation. I notice the tackometer stays at 100 when it is hesitating and at or near 210 when it is accelerating normal Please answer, this is happening more and more! Thanks

Could be the transmission is slipping if not check and test the manifold absolute pressure and throttle position sensors-to include the fuel pressure
