Default new plugs+wires+coil pack CAUSING Stalling

2000 Ford Windstar LX 3.8L, 160,000 Miles

Before Replacing Plugs/Wires/Coil Pack:
1) Running a little rough, sometimes jerky on highway, maybe ONCE a week max it'll want to stall out. Check Engine Lights States Misfires.
2) 3Plugs were clean-ish, 3Plugs were covered/blocks with a TON of crap.
3) After plugs/wires still running rough, removed coil pack, tested it then saw a crack on the side. Replaced it.


After Replacing Plugs/Wires/Coil Pack:
1) Runs smooth above 1.5k rpms
2) Check Engine Light Gone, no codes anymore
3) Below 1.5k (and worst lower) will stall out, read the rest below how it'll stall:

Short Version of Below: Low rpms-- it acts like not getting enough fuel/gas/spark, I believe I ruled spark out. High rpms-- it runs perfect.
Quote:
When starting it, it will run at 3k rpm for about 10seconds, go down to 2.5k for 5seconds, down to 2k for 5seconds, then idle around 1.5 for a full minutes, then idle at 1k for about 1minute (going between 800-1000rpms) then after that minute it will start to stall out. It takes at least a minute to two minutes to stall completely out.

If you keep on the gas (during any time while its on) it will run fine (even when its trying to stall out). BUT for example I run it at 3k (netural) then let off the gas, it'll 'hang' at 2.5k for 5-10seconds, then 2k for 5-10seconds, then 1.5k for 5seconds, then back to 1k & trying to stall. But takes a minute or two before it'll fully stall out. Normally I just turn the motor off 20-30seconds once it begains to stall out.

------
Trying to fix it, its my grand mother's van (and she doesn't have much money...)
------
Someone said maybe cam sensor or shaft? Any other ideas?

I assumed that since no more check engine light, that all the sensors are okay, otherwise it'll throw a code. Or I'm wrong? Whats the IAC again, forgot that one.

And may I say, it was a BITCH to replace the plugs and wires. Took about 3hours.
I did my sister's Honda CRV (plugs wires) 3days ago & was done in 20minutes.

Sometimes it'll throw a code sometimes not...idle air control

Hmm... That sounds pretty good. At the low rpms it acts like its not getting enough of something, since I've ruled out spark, its either fuel or air. Is there a guide somewhere for cleaning that? But higher rpms it runs perfect. Increasing idle, didn't help, just took longer before it'll stall out. I'll clean that out, but its really odd, it idled just fine before changing the plugs/wires/coil.

Maybe since 2-3cyls weren't sparking most of the time (they were really built up, I doubt they could spark at all) then it wasn't trying to 'suck' as much air in before. And now since all six are firing, it needs more air & the IAC is too clogged up? Is that possible/or sound very reasonable djfllmn?

Too late today, I got a can or two of carb cleaner I'll try tomorrow, hopefully it isn't somewhere hard to get to.

Okay I removed the IAC, it doesn't really seem that dirty, it has a little carbon buildup but not that much.
The valve appears to be open 2mm which I don't know is normal, any insight? Too late to clean it & reinstall it & mess with it for an hour, it'll have to wait till morning, but I wanted to remove it & at least look at it.

Grandma please forgive me but I'm gonna bet its a broken valve spring or multiple springs. Pull both valve covers and report back. Brother has a shop and they had one experiencing the same thing. Rough idle, would die without gas, owner replaced plugs, wires, coil etc. If its an exhaust spring your upper intake will get hot, I mean real hot.

Upper Intake doesn't get hot. And it'll run for a few minutes before trying to stall out, 2-3-4minutes. If you give it gas, hold it at like 2.5k it'll be just fine.

I think along with cleaning & testing the IAC, I'm going to spray carb cleaner at the plastic intake manifold cover & gasket. Also will spray in other areas for valcum leak.

However, it would idle find before when 2 cylinders were likely misfiring or barely firing at all. It would idle okay (only once in a while stall out, once a week at idle) but be jerking at highway speed.

Now since all cylinders are firing, it runs great at highway speed, but idles to stall.

^Confusing that the opposite is happening with new plugs/wires/coil.

Key thing: When releasing gas after reving it, it'll hang up & will very slowly drop rpms.

Sounds to me like there is a good chance its a leaky or unattached vacuum hose to me.

With the engine running move your head around under the hood and listen for sucking air (sound like a tire going flat). If you hear one, try to find the source.

Just a shot in the dark, but several times after working on various motors I've had a similar situation because I forgot a hose somewhere.

Good luck.

There is a loud sucking noise, but its always make that nose, coming from the rear bank/firewall. However it seems even louder now, maybe because you have to remove a big section between the hood & window (plastic) making it sound louder.

If anything, I think it'll be the intake manifold on the rear. I've listen with a friend, and we both notice it, but can't pin point it. And can't decide if its the normal sound we've heard before, or louder & something else.

The only tubes I noticed I disconnected was the rear bank valve cover breather tube connecting to the intake, and a vacuum hose to the intake manifold. Looked & looked for anything else, couldn't find anything else.

You found a hose coming off the rear bank or a fitting where a hose should go on the rear bank? Either way, plug the end with your finger while at idle and see what happens.

Oh, I forgot some very important information.

(Grandmother's Van btw)

She was idling in a driveway, and my Aunt was washing off the windshield. On this windstars, theres plastic between the hood and windsheild. Under neath of them is things like the ICA valve, ERG valve, Coil pack, and something class 'DPFE sensor".

She stated she saw sparks & black smoke, this was a few months ago, and is most likely the cause of all of this.

The only thing that relates to black smoke is the ERG valve and DPFE sensor, they are used together (pretty sure) and the ERG valve does something with exhuast gases, maybe the water ruin the DPFE sensors or ERG valve. For some reason I'm going toward the DPFE sensors.

What do this signs tell you folks? Water on windshare, sparks, black smoke.


IAC "Should" Throw an Engine Light Code (Sometimes doesn't)
ERG "Should" Throw an Engine Light Code (Sometimes doesn't)
DPFE "Doesn't" Throw an Engine Light Code, until its fully dead.

So this is making me think DPFE sensor?

Yeah DPFE failure is fairly common, that or EGR valve could cause something like what you're describing. But since the symptoms came on so sudden after other work, I would still think a misplaced hose is more likely, with EGR components on the way out contributing.
