VQ35HR twin throttle issue

4 posts in this topic

Posted · Report post

Hi all,

Recently we did the throttle body mod by blocking off the water supply to them. 

 

While there my mate decided to clean the insides of the tb with t.v. cleaner. 

 

Long story short  it does this weird thing when coming off throttle just under 2000rpm it hangs then comes down. 

 

I've removed battery let it drain of power overnight did the idle re learn etc. Doesn't seem to effect it still the same.

 

Is there any other way to do this.  When my friend cleaned the tb battery was still connected. 

I been reading this not a good idea. 

 

Any help is appreciated

Ever since I bought it the Speedo also does this when reds are on. 

The needles for both Speedo and tacho jump up.  Any ideas on this also?

It does that on the 370.

I think it's the ECU controlling the throttle for emissions purposes.

Not sure if that applies to the 350 though.

      Hey Squad, 350z owner here, haven’t got any mods on my car but hoping to pick up some tip and tricks. Thinking a custom plate would be a good place to start. Never owned one before what do they cost and would all the good combos be taken by now?
