Heavy under load...WHYYYYYY???

Guys, i got a little time to kill and since its raining i'll just ask here.

alright, so my car just started giving me a little problem. while under load at mid range RPM its starts to bug out on me. i know its not the Fuel pump/filter since they are only a month old, i Just changed my spark plugs.

Now, before i go back to the car and start fucking with it, im hoping its not my coil pack. so, any advice before i waste unnecessary time and probably money. i know its lazy on my part. but the car its just going to be mine for a month before i part it out.

thanks ahead to all.

If you're interested ina phone consultation I can help walk you through some possible fixes, and i can be on call to help you fix the issue. I am pretty sure it's your CAS skewed off, pretty easy fix, but most people and even shops don't know how to fix it
