so first my car would bog and stall took it to the shop put it on the scope it said the tps was out of range so i got a new one he cleaned out the throttle body and everything. then he suggested spark plugs so i look at mine and they were garbage so i replaced all 8 . i also replaced some vacum lines. all i have is a bbk fender intake and ive had it for like 6 months, and this problem just started happening. what else can i do , could this possible be bad gas?

Are the plug wires in there correct places. if its a factory roller its a 351w firing order

the o2s caused mine to do it the enige was getting a rich code so it kept trying to lean out. also check that the tps u got is within range also might have to slot the holes to get it to the correct voltage .98-.99

where the headers meet the h-pipe..they are about 3-5 inches away from where they meet

they are on the H-pipe, you should see them pretty easily
