When I got my truck, it was an out of state buy so they do a quick inspection, the cop put the reader on my windows because they were after market tinted, it read 32 and he said, "hmmm close enough". Haha they don't care here.

@Tanner - SC well I do live in the hood now haha. But I traveled a lot and slept in my car a lot while traveling from auto plant to auto plant.

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?

2018-05-01 23:39:02 UTC  

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

2018-05-01 23:42:14 UTC  

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

2018-05-01 23:42:40 UTC  

@sigruna14 no but I think you may be onto something

Maybe you fellas can help a brother out

2018-05-02 00:08:27 UTC  

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

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

2018-05-02 01:00:42 UTC  

@Deleted User It's not carbureted.

2018-05-02 01:01:40 UTC  

@sigruna14 Bad throttle body on your injectors?

2018-05-02 01:02:27 UTC  

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.

2018-05-02 01:03:36 UTC  

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

2018-05-02 01:15:31 UTC  

What year make and model?

2018-05-02 10:38:04 UTC  

@JesseJames 1995 Mustang 3.8L.

2018-05-02 10:39:29 UTC  

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.

2018-05-02 10:39:55 UTC  

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

2018-05-02 10:40:08 UTC  

@Pinochetball Maybe that means something to you.

2018-05-02 10:44:56 UTC  

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.

2018-05-02 10:58:24 UTC  

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

2018-05-02 11:25:56 UTC  

Btw is the MIL on?

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

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

2018-05-02 11:37:17 UTC  

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

2018-05-02 11:38:04 UTC  

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

2018-05-02 11:39:56 UTC  

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

2018-05-02 11:40:50 UTC  

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

2018-05-02 16:09:32 UTC  

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

2018-05-02 21:57:26 UTC  

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

2018-05-02 21:57:53 UTC  

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

2018-05-02 21:59:37 UTC  

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?

2018-05-02 21:59:44 UTC  
2018-05-02 22:00:16 UTC  

No dont do that lol

2018-05-02 22:00:39 UTC  

Youll have massive unmetered air

2018-05-02 22:00:45 UTC  

The car wont even start
