any input helps please..

 

Anybody??

 

Unplug ECU connector A and check whether the Blu/Blk wire at A14 has been moved to A12. Also, has the Orn wire at A13 been disconnected?

 

This has been done as far the Orange wire on the ecu side .its still there but .up in the engine bay its just laying there

 

So yes it has Ben disconnected to answer ur question

 

That's half an answer. What about the Blu/Blk wire?

 

the blue and black wire is connected to one of the wires on the iac plug

 

Anybody???????

 

Stop and pay attention. Check ECU connector A and make sure the Blu/Blk wire has been repinned to A12. Don't bump the thread until you have checked this.

Post pictures of the ECU and IACV connectors.

 

Ron it is repined to a12 the car idled fine..then all of a sudden it started to do the idle hunting even after I changed the iacv..

 

...

 

Anybody..the blue/blk wire is connected as well..I checked the wire with a dmm..nd got 12v on that wire and 10v on the other..so I just ran a wire st8 to ecu pin a12 and did the whole relearn procedure..and nothing can somebody Plzz help me..when I disconnect the iacv the idle stablizes..but when I keep that plugged in and disconnect the tps car runs fine just Damn high idle!!!

Sorry i am new to Photobucket..the wire u see is going straight to the first wire on the iacv connector..

 

Gosh that wiring is a mess you should get some heatshrink from harborfreight as well as a soldering iron for 4 dollars and than get some solder for 5 bucks from radioshack and get rid of that shitty wiring

 

Yes I kno that's next on my list going to pull the whole harnesses out and re do everything..just been busy at work

 

Ok just re did my wires and still nothing!!! Ughh I give up guys I dnt know what else it could be..any sugestions!!!

 

Why is an extra black wire spliced to the Blu/Blk wire at A12?

 

Becuase i was getting 10v on that wire so I ran that black wire to a12 and still got 10v..I got 12v.on the other wire

 

I have no idea what you are saying. Where does the black wire go to and why is it spliced into the Blu/Blk wire? A12 should only be pinned to the Blu/Blk wire.
