Gas Pedal Delay

L8N8

I've had this same exact issue for about 3 months. I bought the car in February and the issue reared its head in May. I have a 2010 6MT w/ Sp pkg.

For about the first 15min after starting the car, acceleration is fine and very responsive. Afterwards, no matter what gear you're in it bogs down for 2-3 seconds when you hit the gas. It doesn't matter if you floor it or even moderately press the gas. Oil temp, toggling VDC on/off, having Smode on/off; none of that matters either. I agree that they all play a role in throttle response but this issue is completely different, since none of those items previously mentioned cause the car to "fall flat on its face".

Nissan dealership will tell you that it's an oil temp issue and recommend an oil cooler. They will also tell you that Nismo is developing an oil cooler that you can buy. Why should I have to buy additional parts to fix an apparent problem from the factory????
