Hey everybody i have a 2000 5Speed Maxima and im having some issues after my header and full exhaust and VIAS delete install i got low boggy throttle response after warm up, bad mpgs,and i tried the idle relearn and now the idle is low and if i floor it as a rev the car cuts off and dies but cranks up fine and starts... Dont know if its the tps, throttle body itself or a Vacuum leak. Here's my mod list

OBX V2 Headers
(EGR blocked off on the intake manifold EGR valve still plugged in)
VIAS delete
Catback ,test pipe, etc

Only has 1 code for the VIAS delete p1131 need help asap guys
Any way to test the IDACV????

 

VIAS delete will do this. More accentuated with the heavier 5th gen chassis and smaller VQ30DEK, (vs the VQ35).

So, how exactly did you do the VIAS delete? Did you just disconnect it only, or did you actually remove the rod?

 

I removed the rod and blocked it off

 

As you stated in the other post, might want to check your TPS.

 

You think a bad tps would cause idle problems?

 

All those items aside from the TB you said could cause that, in addition to the IACV, which is a scary arena due to the frying of the ECU.
