have a b16 in my 89' si and it didn't run right one day and i figured out that one of my injectors had shorted out.. so i replaced it and it started and would idle fine... now its came to another problem.... it will start and idle but when i give it any throttle it bogs and cuts out and will not rev past 2500 rpms. i have put in a new o2 sensor, fuel filter, new plugs, plug wires, distributor, cap and rotor, knock sensor.... but it isn't throwing any codes...i had a guy tell me that it was my TPS but i changed it out with a different throttle body and it didn't make a difference...and i had a buddy of mine say it could be a plugged cat, but what do you think???? I'm out of options and need help please.... could it be a problem with my fuel system becuase just before it started this mess, my gas gauge stoped working????

 

Maybe you replaced an injector but tha real problem was fuel pump? Speaking from experience, don't figure anything. Go by facts. Facts taken from testing. and researching. Seeing as how yur gas gauge stopped working I'm thinking its a fuel pump problem. Anyone else got any ideas?
I hate to say this and I'm not saying yur dumb juss askin. Does the car have any gas?
