Yeah been rebuilt and pcv valve is blocked off it has a carch can instead

ok so it looks like it may be the iac it goes up to 90 in its position but im not sure how to change its position at that temp range etc to see if it can be causing the issue

[vt3.8lt]

Seem to have figured it out i swapped the iac out for a spare i had there and now it idles to low going to have to do some fine tuning with it to see if i can get it to idle propperly

[vlad01]

sounds like the IAC might not be working at all. I would check the wiring going to the IAC. Put it in diag mode and see if the ECU is driving the IAC.

Cool that sounds like a good idea exept im nit sure how to put it in diag mode i did make some changes to a couple of sliders with the new iac installed and it seemed to do something but i didnt have the time to look into it properly

Well still having trouble with this thing it was idleing fine but the bin that was loaded in the nvram sent back 0 values on everything so i loaded a new bin to it and now it wont update anything and the main bin of the board have switched bins and it starts and runs somewhat but the odle is still an issue im not sure wich bin scalar or flag i need to adjust to make the iac do its thing properly it just seems to act Iradically

[vt3.8lt]

Im gonna try n put all my accessories wideband etc onto a relay or better power supply as its been messing with yhe connection for the nvram for a while and will most likely well hopefully be whats causing the bin 1 side of it to not write and only read well that my plan for the weekend as i dont get home from work till late if anyone has anyideas what may be causing it id be grateful for your help thanks dane

[vt3.8lt]
