When the car gets hot and I am stopped at a light, the car won't pick up when I try to go again, it stutters and then when it finally catches it goes

I recently replaced the torque converter, a coilto fix the problem and the battery. I know the alternator is good.
It used to happen all the time, but now seems to happen only after it gets hot, which doesn't take to long considering I live in FL. It also happens if I have to hit the brake on the highway.

Did you check for trouble codes?

Such symptoms are usually something to do with the throttle position sensor, ECT and MAF.

It wasn't put on a machine yet-working on getting that done, but when Rob checked it,he said it came up w/ all 12's? He said that meant that nothing was wrong on that end, Is that true?

He said they are go codes, that everything should be fine w/ the computer. I just had to put on new caliper,rotor, and new brake pads.(Caliper locked up)
Could it be the spark plugs andwires causing the issue? One of the spark plugs is arcing out, he took it out and it didn't look bad, but I am going o have them redone this weekend-if I have money.

He means that only Code 12 is present therefore system is good.

The calipers locking up can cause lack of power due to the brakes sticking and symptom description does fit. If you have a fault with the brakes, that should be on the priority list.

For the spark plugs if they don't look good, replacing them would be advised.
