Question 01' LS430 Major Acceleration Delay

Stupidly, i was going at a high rate of speed down a curvy road, when my back end slid out and i heard multiple beeps from the dash and a check engine light suddenly appearing.


now, when i start my car and drive it for around a mile everything is fine, suddenly out of nowhere, acceleration is suddenly difficult, it takes a while to get to speed and when i full throttle the engine will rev as high as it can go however the car will barely accelerate until it hits around 3.5-4k RPMS.

again, it works completely fine until i drive it for a mile or two when this happens.









any help?

You need to read the codes from the ODB2 connector. If a Check Engine Light is showing then it should have thrown a code.
May also be worth disconnecting the battery and leaving it for 15 mins before reconnecting it to reset everything.

took it to autozone yesterday to check codes, and its throwing a knock sensor bank 1 code, and a vvt solenoid code, maybe its the solenoid?
