Re: I've searched found nothing any help be great

So just do a proper search: On 'Idle Control (Valve)' and/or 'IACV' maybe...
because your ECM thinks that (valve) is open circuit ?

Edit: I just googled 'Idle Control Valve' and 'IACV';
3.8M and 500K hits respectively..... and even just
'Idle Control System' gave 13.6M hits.... H T H !!

IACV via 'Search' gives 84 hits, including this one....
This big clue (red arrow) is from one of those, too:

Wow, you waited a whoppin 2.5 hours to bump your own thread? I can totally understand frustrations but bumping and duplicate postings are not going to get you any further than giving folks a chance to read your thread and respond IF they are familiar with your issue. Naturally it would be helpful to know what lead up to this, what you have done so far and your engine info as far as mileage etc.

I searched p1508, idle control,etc. . didn't really see thread on what exactly to do, just trying to do what I can in my driveway,trying to save time and money. No disrespect to anyone on here. Any help be nice. I don't want to mess up anything.
