HR/Hesitation/No CEL/EMR/VTC Cover

[Neal376]

Hey, I have an HR 6mt G35 sedan 2007

I have had this strange hesitation at part throttle high gear for a long time. AFR's would spike and the car would jerk. Car also had a poor idle.

Well, I recently unplugged the two sensors connected to each VTC cover and drove the car for 2 weeks with the CEL illuminated with the appropriate codes. No hesitation, great idle, everything is absolutely dandy (except for the power loss). I bought the car second hand, and I didnt know the VQ could ever run so smooth. Cleaning behind the covers, and re installing does not help.


Looking this up, I found that these covers cost a sweet 500 bucks a pop! Now does anyone have any experience with this, or any suggestions before I drop a grand on this repair? Did nissan redesign these covers?


thanks for any input

Did you clean the throttle bodies? They are SUPER-sensitive and can be damaged if you touch the butterfly valve.

well, yea. they are kept clean. I see no reason to suspect anything else if the situation is corrected by unplugging the EMR like I said.

many dealerships sell their car parts on ebay or with a "discount" website, so you would save money just by ordering the part online instead of walking into the dealer's parts department.

yea^ thats what I did. but i called up first and found out nissan only redesigned the passenger side one. so i will replace that first and see how it works out.
