Default i hate cars

Alright so I thought it was my fuel pump messing my car up, got another one swapped it in and still runs like garbage. The only thing it did was add a gas smell. So now after checking a million things I'm at a loss.

Now onto the problem, it bogs down really hard at full throttle and low rpms. It feels super laggy to any throttle really and once in a while it just won't start without hitting some gas.

The last thing I can think of is fuel injectors....maybe? I guess I wouldn't post this if I knew.

if its a single cam, check fuel injector o-rings seriously.

sounds like a dizzy problem to me.
make sure your coil is good.
then, might as well just replace the cap and rotor.
get new wires.
new spark plugs.
make sure the timing is right.
Might even have to replace the dizzy itself if the CAS has bad or if something really dumb, like the shaft is bent.

Was getting ready to do my dizzy next check. I'm just in a bit of a bad situation so id rather try to pinpoint things vs change everything.
