So I've been cleaning out my engine lately because it was terrible looking. Th idiot who owned the car before me did not care for it at all...Anyways today I realized I had a loose connector to the number 6 injector, and I noticed I have three different kinds of injectors.

My car has been bogging down and has had no power, it even has trouble making it to the amazing speed of 20 MPH. Could the different injectors be causing this? It's a long shot but I figured I'd ask.

BTW its a L98 if that matters.

 

it could ..but since you have a 350 i think they should be 22lb injectors stock ..to check your injectors ohm them out.... i think 14-18 ohms

 

If they're different they could have different flow rates. If any are higher than you could be washing out that cylinder. If some are too low then you could be running that cylinder lean.
Ohm them. Also get the part numbers off of them and see what you can find out. The ECM only knows what it's been told about the injector size.
