It has a code 14, and it stutters at light throttle only.

For the code 14, i thought i fixed it when i went by a diagram i have...
i converted the 3 wire iacv to a 2 wire

I moved B6 -> B23 and i pulled B15 for the ECU plug

On the harnes, i pulled the orange wire (that goes to B15) and disregarded it

I moved yellow black -> green black on the new iacv plug

I moved black blue -> black on the new iacv plug

i did it all right, only thing is i think the instructions i followed were for a obd2b integ/EX/SI ECU, and we are still runnign the stock P2E, is that my error rigth there?

Next issue i have is the throttle...

the car runs fine, not on limp mode and not throwing 7 cel's (well, it threw that and more, but i fixed it all already ).

Basically it kinda stuttres at light throttle when u hold it at about 15-20% throttle like if its on limp mode or like if it was hitting the rev limit

Its not in limp mode, because after u past that point in the throttle, that goes away and the motor revs freely

so anyone have any idea?

 

Did you actually change the ECU or only the manifold? Because the Y7 ecu is looking for a 3-wire IACV regardless of whether you've rewired it.
I did the exact same thing and had to swap the throttle rotor & spring over to my Y7 t/b and put it back on, and repin it back to stock wiring setup. Until later on when I go to the OBD1 conversion it'll stay that way.

Hey you live in Vista! I graduated from Vista High all the way back in 1991...

damn yeah were going to convert the car to obd1, so i guess were screwed till we convert...

we kept the P2E, all we did was swap in teh z6 intake manifold....

damn 91? haha u might know some of my cousins...

 

upp for my second issue...

 

I think the second issue may be related to the first issue. Whenever I let off the throttle the car would bog a little, and when I pressed it again it would surge or stutter. I think because it's starved for air with the IACV not working and when you even hit the pedal slightly it gets a rush or something. That went away when I put the wiring back to stock.

 

damn...i guess we need to conver the car to OBD1 ASAP...hahah
