hi guys,i have a k20a2 eg with a us spec kpro installed,i had a p0134 code,so i bought this sensor off ebay,item number 130371089969 .installed it and its doin the same as the origanel sensor did,coming up with a cel,but this 1 runs lumpy at low revs when driving,my origanel sensor was a denso japan 1 with 103 near the threads.do i need a us spec sensor to make it right??

thanks guys

You need the primary O2 sensor form an 02-04 RSX. You could also have a wiring fualt.

thanks for the reply,wires have been checked and are all good,running a hybrid harness with us spec kpro version 1.2.24
will updating the ecu help??

You should always use the most recent version of software.

im getting the car a fresh retune next month i was just wondering if i should wait till the day i get the remap to install the new 02 sensor just incase i brake this 1 too.?

hankyou for your help

Don't assume you broke it... it could be wiring (broken lead, intermittant connection, etc.)
