DIY: Clean your throttle bodies
#497
I took off the filters to wash them so thought id just clean the tb from the front only while i waited for the filters to dry given it was so cold and i didnt want to spend an hour cleaning them by having to remove them like last time and i dint have replacement o rings either.
Anyways i was actually able to squeeze my finger through the TB to be able to clean it very nicely from both sides and i moved the living daylights out of the butterfly valve to clean properly from the inside at times holding it open with one finger while cleaning and did not have to reset anything and have rock solid idle again and smooth acceleration.
While its best to removejthe TBs to clean properly Just a note for those who are afraid to take off the TB or have time constraint you can do it without removing it and you still get the same/similar results and hopefully you dont have to reset anything after BUT i can not guarantee that given the inconsistent history of this thread so do at your own risk!!

okay guys I need a little bit of help. I went thru and cleaned my throttle bodies without disconnecting the battery or the harness. I did open/move the butterfly slightly to clean in/around them. I drove around for a bit and it ran fine but then threw the P0507 code.
I have done the peddle dance couple hundred times without any luck. I did get it once but when I turned the car off and restarted it couple mins later, the light came back on. Last night, I disconnected the battery and both harnesses over night and did the reset/peddle dance today morning without luck. I have finally got the car to idle around ~800rpm, but my CEL light is still on. I'm scared to try the peddle dance again because I finally got the RPM correct. Would driving around for a while make the CEL go away or getting a scanner tool and erasing the code work?
If anyone is in DFW and would like to help me do the peddle dance this afternoon or next couple days, that would be great (just send me a PM).
And if anyone is in Houston and would like to help me next weekend or a weekend after that, PM me. (hopefully I can get it fixed before that)

Here ya go try this. I did this and it worked perfect. https://g35driver.com/forums/g35-sed...-cleaning.html

my RPM stays stable around 750-800rpm. I was able to get a scanner and erase the code, then drove 250 miles (Houston to Dallas)... CEL stayed off and idle seems good, even thou its not down to 650. I think I'll stick to this rather than trying to mess with it again and getting stuck again.
the 250 miles was at about 80mph and I averaged 23-24mpg, is this normal?

Yeah I was just cruising. I reset my mpg gauge when I first got on the highway. First doing 70-75mph I was getting ~24-25mpg but once I started doing 80mph I was getting 23mpg. I had my ICC set most of the way. What could I do to improve my mpg?

ICC = intelligent cruise control.
When you say service? what kind of service are you talking about? I need to do an oil change because IDK what kind of oil the dealership used. Brakes should be good since the dealership replaced them before I bought the car. I've only had the car for two weeks now.
back to topic about the RPMs... After getting to work in the morning and putting my car in park, I noticed that my RPMs were around 650-700 range, so that's good.

That said, 23mpg for our cars is pretty good.
I've monitored my mpg, along with mods and its effects on it, for the past couple hundred tanks of gas, there's really not much you can do to change mpg significantly.

https://g35driver.com/forums/g35-sed...-cleaning.html <<< here is one of the links to the procedure. If you do your procedure right after you clean the throttle bodies before turning on the car, then you should be able to skip the parts where he unplugged the battery and harness.
