Car Jerking when Accelerating

Yes Monkmon33, you are correct in that light everything you state is true.

I was just referring to fuel level in tank in stock based applications as being the cause.

In my experience modifications done by many DIYs that are not done with a lot of thought in mind in that overboosting, insufficient fuel delivery and/or proper safeguards being taken usually lead to fuel starvation and resulting engine failure due to detonation.

Whilst properly built and maintained vehicles very rarely do. A bad fuel pump, clogged filter, injector or failure of control system would be one of those. Although blocked filters or injectors can usually be attributed to human error.

BTW-The IMSA and Firehawk cars were stock FD3S so it is a testimony on how well engineered the factory vehicle is when maintained properly.

So actually we agree, not enough fuel NA or turbo will cause the round motor to rattle resulting in $$$ for your local builder.
