i have a crx with a b18a1 cable tranny stage 4 clutch

my issue is a studdering problem

the car idles perfectly seems to run good

1st gear is fine as well as 4th and 5th

2 gear at 5000 rpm it starts to studder
and i shift to third and 3rd at 3000 rpm it studders

other than those 2 gear the car is fine

the tps at closed throttle reads 5, 0, and .37 on the signal wire
open throttle 5, 0, 4.45 on signal

can figure out what it is

i do not have an o2 sensor by the way

could that be my problem

 

yes, not having an O2 sensor is probably 99% likely your problem. fix that.
