2jzge Na-T loping idle

[Fletch124]

Im having some problems with the idle on my 2jz Na-T project with 7m electronics running MAFTPRO. I went over the entire system post throttle body for leaks. Couldn't find a thing besides one semi-loose bolt from the upper plenum to lower runners. Pretty much all of the vacuum ports are capped off besides the necessary ones.

Its got to be a big leak(if it is a leak) because if I take a post throttle body hose off the loping doesnt get much worse.

Im using the 2jz TPS, just extended the wires to the TPS and IAC. TPS voltage on MAFTPRO are >.58V.

Help!!!

No idea?

any codes?

any codes?

The normal codes caused by the MAFTPRO.

And 43... "Starter signal" Huh?

hmm that starter signal is weird. What do you mean normal codes caused by the MAF-T Pro, the only code I'm aware of is the AFM code. You shouldn't have that code if you installed the resistor right?

Yea I dont know what would cause that starter signal code. Anyone else?

Yup just 24(Air intake temp*AFM), and 32(7mgte Hac sensor). It wont turn the light on ever, only appears when you check codes.
