Default torque fluctuating

I need help with my camaro z28 (year 2000).

The torque fluctuates when the car stands e.g. in front of a traffic light or in an drive in. then the automatic drive is in level "D" an i just hold my foot on the brake. after a few seconds it begins to fluctuate.
sometimes the engine brakes down...

it happens only with a warm motor...

has anyone an idea? thx a lot!

Does it sometimes stall when coming to a stop?

If so,
1. check your tranny fluid.
2. your torque converter could be failing. Next time it feels like it's gonna stall when stopping, downshift manually, 3-2-1, and if it stays running, your TC is the problem.

Otherwise, check your fuel pressure, fuel filter, air filter, plugs, wires, cats.

I assume your post means that you are getting a surge at a standstill? If you don't feel the surge when you are in Neutral, then its the torque converter.

The reason: wrong plugs (cheaper one)
The solution: new AC Delco 41-985 installed
