I checked most of the vacuum lines I could see visually and saw nothing loose or cracked. Not sure if there is any other way to check them? Tomorrow I will check the MAF sensor. Let me say that I could just be over the top on my expectations because the car does not stall, it just has a slight rough idle at stop lights. It does not seem to respond instantly if the car is in D from stop. However it is much better if I start out in 1st gear and shift through them. I appreciate everyone's time and suggestions.
Do a throttle reset. Turn the ignition on but don't start the car.
Depress the fuel throttle and hold to the floor for five seconds
Release the throttle and turn the ignition off but leave the keys in it.
Let it sit for at least two minutes.
Now, start the car. Reset complete.
It should eliminate that hesitation. At least back to factory performance.
Next, Get a Sprint Booster.
I'll bet this is happening during warm weather with you AC on? And I'll bet this is your first wireless throttle.
