i 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????

 

WOW NOW???

 

There are 3 main components that your car needs to run.

Fuel

Air

Spark

So far you have checked one.

 

i had a similar problem with my crx si w/jdm b16. It wouldnt rev past 3500. ultimately it was my ecu. I converted it to obd1 and threw in a stock p30 and it was fine. Try pluging in a different ecu./

 

Limp mode yo. It sucks. Any CELs? Check your ECU.

If you're throwing a TPS code, you need to adjust it.

.45-.5v closed throttle
4.5-5.0v open throttle
