A:With reference to your inquiry on the Denso Oxygen Sensor - Direct Fit - part# 234-4087, the EGR valve and or even the oxygen sensor may be the possible cause of the problem on your engine. However, without the presence of the vehicle we could neither diagnose the problem nor provide you with a 100% answer. I would suggest you to get assistance from a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.
