I drive an 01 s2k 55K mi. 3 inch hi flow cat and apexi n1. Stock motor. Was recently supercharged, IDK if the car has a upgraded fuel pump. When I was boosted I noticed the problem. When I would punch it it would bog down, but when I let up on accelerator it would tk off. I thought it was a boost lk, but never was according to my guages. I would add fuel additives/octane booster and it would clear it self out. Now I can punch it and it will jump and bog and backfire. I may have gotten into some bad gas in TN with ethanol, IDK wat the deal was. Its an intermittent problem. Could be dirty fuel filter? A bad fuel pump? Its now starting to die if I rev at a stop. Maybe fouled plugs? Which steps could I tk to diagnose?

 

 

Spell the words out! What is tk, idk, and lk?

 

Tk=Take "but when I let up on accelerator it would TAKE off"
IDK= I don't know.
lk= leak "I thought it was a boost LEAK"


Just helping things along :-)

 

Thankyou I had no idea what TK and LK were supposed to mean or if he just hit the buttons accidentally
