i swapped a jdm b20b into my 94 ex civic coupe, and it ran really bad, untill i fixed a few problems. well when we fixed most of the problems

we were stuck with 2 CEL codes. it was the tps sensor and the 02 sensor. well i re-wired the o2 sensor and changed tps sensor and it ran even worse.

the problems i am having is that it sputters when i am giving a little throttle. i am stuck on what else it could be. any help would be greatful..

 

purge valve solenoid

 

tps has to be adjusted upon replacement. your going to need a voltmeter. your looking for .5v at closed throttle, 4.5v at WOT.

as for the o2 sensor... what code is it ? heated circuit or sensor circuit ?
is it a oem sensor ?

 

TPS out of adjustment can make a lot of issues
