Privacy is an American tradition

Inspections are gay. If your state does inspections then you live in a commie state. Also I tint all of my vehicles also.

@here My car normally idles at <1000 but today on the way home from work it started idling at like 2000. I figure it's gotta be some kind of vacuum leak but I'm not sure how to find that, other than spraying flammable substances all over the engine which I'm not too sure about. Anyone have an opinion on whether this is safe to drive like this?

Mark Vandal 2018-05-01 23:39:02  

@sigruna14 have you tried turning it off and back on again?

sigruna14 2018-05-01 23:42:14  

@Mark Vandal Have you tried shaving with a propane torch?

Mark Vandal 2018-05-01 23:42:40  

@sigruna14 no but I think you may be onto something

Maybe you fellas can help a brother out

Pinochetball 2018-05-02 00:08:27  

Propane is the safest way to go, or a static smoke test

@sigruna14 IS it carbureted? Possible just a stuck throttle?

sigruna14 2018-05-02 01:00:42  

@Deleted User It's not carbureted.

Deleted User 2018-05-02 01:01:40  

@sigruna14 Bad throttle body on your injectors?

sigruna14 2018-05-02 01:02:27  

I mean, it could be a lot of things. Hard to know where to begin our if I should just let the shop deal with it.

Deleted User 2018-05-02 01:03:36  

well if its just a stuck throttle that's a pretty easy fix

JesseJames 2018-05-02 01:15:31  

What year make and model?

sigruna14 2018-05-02 10:38:04  

@JesseJames 1995 Mustang 3.8L.

sigruna14 2018-05-02 10:39:29  

If it means anything, first I noticed it was rolling down the other side of a bridge in 3rd at 35, so revs were a little high, I was using the higher revs to help keep my speed down.

sigruna14 2018-05-02 10:39:55  

When I put it in neutral at the traffic light I noticed the revs were still up and I was like... Uuhhh... Wtf?

sigruna14 2018-05-02 10:40:08  

@Pinochetball Maybe that means something to you.

I would remove the throttle body and clean it with throttle body cleaner. And remove the mass air flow meter and clean it with MAF cleaner.

Pinochetball 2018-05-02 10:58:24  

Yeah like a i said last night youll wanna remove that plenum and visually inspect the tb to make sure its not sticking open, and remove the iac to make sure the pintle isnt sticking open

Pinochetball 2018-05-02 11:25:56  

Btw is the MIL on?

sigruna14 2018-05-02 11:31:19  
sigruna14 2018-05-02 11:32:55  

Btw, since the IAC is what the computer uses to adjust the TB, shouldn't the problem have gone away when I unplugged it?

Pinochetball 2018-05-02 11:37:17  

No lol the computer adjusts the pintle in the IAC on idle to keep it smooth so it doesnt surge. If its sticking open, like mechanically stuck the ecm wont be able to adjust it and the idle will be high

Pinochetball 2018-05-02 11:38:04  

Most the time when they stick they stick just a little open and the car surges or it sticks shut and it wont idle at all or it will but super low

Pinochetball 2018-05-02 11:39:56  

If the cars at 2000rpm unplugging it wont matter anyway because youre off idle

Pinochetball 2018-05-02 11:40:50  

Ill be at work in a few mins and ill email you some Identifix test plans real quick so you can mess with it today

JesseJames 2018-05-02 16:09:32  

To bad it isn't obd2 would be much easier to pinpoint. But I agree I would start with tb and or iac

sigruna14 2018-05-02 21:57:26  

@JesseJames It is OBD2 but all I have is a basic code scanner.

sigruna14 2018-05-02 21:57:53  

Also there is a sticker on the TB that says not to clean it because there is a special coating.

sigruna14 2018-05-02 21:59:37  

If it's the IAC pindle sticking that's causing this, should physically removing the IAC from the TB and then starting the car make the symptom go away?

sigruna14 2018-05-02 21:59:44  
Pinochetball 2018-05-02 22:00:16  

No dont do that lol

Pinochetball 2018-05-02 22:00:39  

Youll have massive unmetered air

Pinochetball 2018-05-02 22:00:45  

The car wont even start

Pinochetball 2018-05-02 22:01:30  

Ok if the TB says not to clean it, then just make sure nothing is keeping the blade open, but id take that IAC off and clean it real well

Pinochetball 2018-05-02 22:01:58  

Sorry i didnt get a chance to send you any test plans, today was busy as shit
