Just bought this rig and tried to clean tb. Long story short: 03 automatic sedan, cel high idle, down shifting harsh, ecu reset did nothing new tb same as it ever was. I don't know what to do. Please help! Car has stillen cai and exaust and I plan on throwing down md 5/16, hfc, teins, and having it tuned. Can I continue to drive it a couple weeks until I get the mods done and bring it in to be tuned without doing damage to it?

 

how did the car run before tried to clean the TB?

 

When I would start it up the rpms kick up to 1500 then drop to nearly 200 then even out at 700. Keep in mind that I'm in mn and it's cold so I thought the idle should have been higher for warm up. So thats how it all started and after all this it seems pretty minor now. Hind site is a funny thing. Besides that it was running top of the food chain, aka: great. As much as I didn't want to I brought it to the nissan dealer since the infiniti dealer already bent me over to the tune of $230 for a high mount stop light and it only has 2 leds but apparently thats the oem replacement. I am currently at the dealer and they don't seem to have a clue either. Thats why they make the big bucks?

 

i got a throttle body i will sell you . its off a 04 fx35 which i am 90% sure it is same as the g35 ones pm me

 

You needs to do a full reset...ecu, open/close relearn, idle air, etc.

There is a DIY on here somewhere.

 

Sounds like they got it figured out after remapping ecu or what they call adjusting all kinds of settings. So I guess I also have a used tb for sale if there are any takers. I have to give respect where it's due. Mad props to nissan in white bear. Thanks for the info, this site is the ****e. Now on to the mods.
