hey, i just swapped my h23a1 to a jdm h22 and its running REALLY rich, i'm still using the h23 throttle body though, could it be smaller than the h22 TB maybe and thats whats causing it to run really rich?

Its true, the h23 throttle body is 3-4mm smaller than the h22s. However, what ecu are you running? I don't really think that a 3 or 4mm smaller throttle body is going to make you run very rich. So yea, what ecu are you running?

 

h23 and h22 tbs are the same size

 

runnin a p13

no, something else is wrong

 

when i was running really rich, the problem was a bad cat....

 

how would that cause you to run rich? the o2 sensor is before the cat...

 

O2 Sensor, leak in vac lines, or sticky injectors can cause a car to run rich.

 

i dont think it's the o2 sensor cuz everything ran fine on my h23 but as soon as i swapped it, it ran rich, maybe it's the injectors... how can i check to see if the injectors are sticking?

 

how do i check my injectors? anyone?
