Oh thats cool you must have a modified ECU. I hope it keeps doing that for you. Maybe some day your throttle response will be almost as good as a well tuned carburetor. if you spend enough on tuning it. ONly if DMCA will allow it, that is:

Have fun with your EFI when it becomes illegal to tune it

They are stock, actually and I have zero issues with throttle response, on all 5 of them. And that will never get passed just morons in the government trying to idiot proof the country.

Wanna bet? here is a deal for you. If that gets passed, I will mail you a 4 barrel carb and a megajolt ignition controller that you have to run. If it doesn't get passed, I will downgrade my car back to fords PATS laiden, hanging idle, messed up IAC, inconvenient fuel pump location and price-- ECU and EFI

Hanging idle problem on 2002 mustang gt

I don't need a carburetor, I've got more than enough of them. So swapping out my fuel injected supercharged system for a carb system, ha... ah nope. I'm not switching any of my cars over to carbs, and I never will. You won't convince me sorry. Try your deal with someone else.

Lmfao, I love that guy. I bet he had no idea how popular he'd become just some crazy hairdo, and a facial expression. Funny thing is that actually happened to me. Fixing the Carter off my Impala and the Edelbrock crapped out on me.

"crapped out" lmao yeah im sure that was a HUGE repair bill. There is literally like 3 moving parts in a carburetor and the most expensive one is probably $.75 and takes under 10 minutes to replace if you have at least one tool that remotely resembles a screwdriver

Woah, I had no idea. Man that's a real game changer. My mind is blown; I never knew that at all. Well I guess I'll change the rest of my cars to carbs. I mean it's just so much better. Oh wait I forgot that I don't care at all.

I don't consider it obsolete until something comes along that can make as much or more power. It also has to do it without bringing significant down sides if somebody does invent something like that, but they havent.

Hanging idle problem on 2002 mustang gt

Oh yeah that's good, that's real good. Alright, I think you should tell the big 3 that they've been producing the wrong intake set up for the past 25 years. Make sure they know carbs are better, we want the best from the manufacturer. Hopefully they'll see the error old their ways and go back. Maybe we'll see the return of the carburetor! Oh, who am I kidding that's not ever going to happen. My guess they found something better, go figure.

The feds told them they had to stop making carbs in 1986. The 1986 mustang GT had less horsepower than the 1985 carbureted one. It also had a revised cylinder head and I believe it had more compression.

Carbs haven't developed much in the past 25 years and they still make more power all things being equal

Evolution doesn't involve making the inferior traits be the industry standard just because they are new.

The 5/8" hose attached to the PCV valve had a long split on the bottom. After, replacing that $1.49 hose, I have no hanging problem.

My idle runs around 600 rpm, but the ECU will relearn the correct idle in time.


Smoke tires, Not drugs!!

Nice! It feels great to actually find something you can fix when it comes to 4.6L idle issues lol.

2000 RPM's is a bit high though. It probably is your IAC. Cleaning them typically does nothing because they are usually worn out by the time that they get dirty enough that they need to be cleaned.

If you do determine that the IAC needs to be replaced, I recommend purchasing one that is manufactured by either Motorcraft or Hitachi as the other makes seem to be very troublesome.

I learn something new everyday, interesting read bullit

Hard to know when this guy is being serious or just trolling.

Hanging idle problem on 2002 mustang gt

sounds weird, but basically, as the clutch would engage and disengage at a stop light, my rpms would bounce between like 900 rpm and 700 rpm (clutch engaged vs disengaged, respectively). after it would do that, the ecu would act like it was having an idle problem, and thats when it would start hanging rpms. An ecu reset always fixed the issue. then charging my a/c allowed the rpms to jump to 900 or so when the clutch engages, then slowly work its way back down to normal idl, and stay that way since the clutch stays engaged.
I havent heard anyone make that connection before, so i have no idea if its the same for anyone else with a hanging idle. but i kinda feel that in my case, its the ecu attempting to correct something, more than a failing IAC. (havent changed mine, and its working find nowdays.)

Funny you say that, I've actually started using my ac a bit more due to being summer and not wanting the girls to complain, but I have noticed that my exhaust is a bit quieter when my ac is on. And on random occasions it'll be louder on WOT with the ac on, strange isn't it?

All hail the carburetor! It is pretty silly that the big 3 are now using inferior technology for us.

i know im pretty late on this, but just wanted to point out that with freon at the proper levels, i have not run into this problem at all since. i dont think i have ever WOT'd with the a/c on.
strange enough, My exaust is louder with the a/c on. if your's is louder with the a/c off, then i would imagine that WOT cuts off the a/c, which is why yours goes back to being loud again.
