Re: Car jerks at 5000 RPM, Jake, Joe?

do you get black smoke out the back?

with the upgraded fuel pump you could just be running to rich at the high rpms. When this happens on your a/f gauge is it sitting in green(rich)?

if so you might just be running rich and your car may not have been tuned up that high.

afpr or/and tuning would fix this.

had similiar prob when i got my car back from shop originally. only thing that fixed it was a aeromotive fpr and driving around and tuning.
