Default Why does my car do this??

Ok when ever i get 1/2 throttle it tries to bog out, but if a hit hard it comes alive. what can i check?
Also it hard developed a valve trian knock?how do you solve this by compression drop, how do you adjust the valves??

If it was carbed, Id know the prob, but since it says 90 in your info, youre FI.

It could be a few things, fuel related, spark related, or air related. Sounds like a fuel problem because of your positioning of the skinny pedal.. check your FP first, that could lead you somewhere

As for the valves, you have to remove the VCs, and its kinda obvious from there if youve done it before

try cleaning the maf sensor or run a koer test and see if any codes come up, there may be an issue with the tps
