HELP! Severe acceleration lag

Ren425

Been a couple years I suppose since people have been on this thread.

Just curious and would like input from others about possible issue I am facing. I've owned the Z since the beginning, and this issue just came about.

Z (manual) drives like a champ up until the oil temps reach around 220-230. I live in LA and majority of the time is stop-go traffic.

As soon as the lights turn green, I get this hesitation from the Z between 0.8-3K RPM. It's most definitely hesitating/lag, if you're an enthusiast, you would know how your car responds to your driving, but in this case the car hesitates to accelerate. Once it reaches past 3.2-3.5K RPM, as if nothing has happened. It's a strange sensation.

I've read up on oil pressure for VVEL, brake switch, etc. was wondering if any of you would have further insight. No error codes, ECU was reset. I'd truly appreciate any insight if you have experienced the issue or know the cause and solution to this issue I am facing. Cheers
