sorry dcotter.. i know my girlfriend said the dealership told her bank 2 was the passenger side but the more i read about it online i find that what you said was right and i was wrong. bank 2 is on the side with cylinder 2 is what i have been reading and what you said.......

 

rule of thumb the #1 cyl also bank 1 will be the closest spark plug to the front of the motor.

 

its fixed...p0175 code was caused by incorrect cam timing. the intake and exaust cams were not lined up correctly. reset the cam marks and it runs quiet and smooth........thanks for the suggestions.....ron

 

Did you ever discover the reason for P0175 on this car? And if so, how was it corrected?
