I uninstalled my ID2000s and put in 1000s. I can get the car to start up and idle perfectly. Only problem is when I blip the throttle the car just completely dies. when I raise the throttle very slowly it stays alive. I have a FP gauge on my IP fuel rail and it sits at 30psi when the car is idling (45 with vac hose disconnected). and I have watched the FP raise when I slowly raise the throttle. Any ideas?

I'm also using a basemap that Ptuning sent me.

 

whats it idling at?

 

Idles perfectly smooth at 1000 rpms @13.7-14 afr when fully warmed up

 

FWIW my car does the same thing (albeit randomly)

 

What happens if you lean it out? You have another full point you can go to be at stoich which is where it should be idealy.

Does your fuel pressure drop by chance when you blip the throttle? 30psi seems a bit low.

 

Ive added fuel and removed fuel and it didnt change anything.
It runs at 45psi with the vacuum line off of the fpr. Which is what it should be right?

 

Possible IACV issue? Have you cleaned it recently?

 

Hmmmm i kind of think it may be the oacv also... Gonna try and pick one up from for sale forum..

 

Are you going to be selling your ID 2000's? If so shoot me a price, I may be interested.

 

Is the car fully warmed up?

I've noticed mine will do this too sometimes, but its only when the engine is cold (<110*F coolant temps). As soon as its up to normal running temp the problem goes away.
