5.4

This van has been brought to me.
1. Was running rough and had a miss fire #5 and when checking found coolant in the #5 spark plug hole.
2. I am told several items were replaced.
3. intake manifold gaskets upper and lower, it has the aluminum intake not plastic.
4. replaced spark plugs with factory correct.
4. Replaced all fuel injectors.
6. replaced all coils.
7. Replaced knock sensor.
8. Replaced CHT cylinder head temperature sensor.
9. Cleaned MAF sensor with MAF sensor cleaner.
I'm not sure if anything else was replaced.
Now here is the problem, after all that the van runs bad and will die after a few minutes,

It will start and run when cold but as it warms up it gets worse and if the trans is shifted to any gear it dies almost immediately.

After it dies out then to get it to restart it takes wide open throttle to get it to start and it runs rough and will die if throttle is released.
Exhaust is very bad smelling. Rich.
The only code is reediness p1000

MAF reading is high, absolute throttle position is a bit high, coolant did not reach temp, intake air was low.

I smoked the intake and didn't see any big leaks just a little from egr and idle valve,
(not sure if that is the idle valve but it is a silver cylinder with a black plastic cap, about a half inch round)
I will add a picture this weekend.

I did some scans but never achieved open loop and coolant temp threshold.
I attached some screen shots and I will look at it again this weekend.
Thanks and if anything more is needed let me know.

Plugged exhaust?

 

[jigfeett]

Thank you, no I dropped the exhaust before the CAT for testing and no change.
I appreciate the thought, I will be going out today to look at it again and try to run it long enough to get better readings.

I have factory info if you need something. You did not do any of the work that was performed?
Also some basic number would help. Fuel pressure, compression etc.

Are you still getting coolant in cyl #5? You did not replace the intake gaskets? Have you performed a simple vacuum gauge testing?

 

[nickb2]

ok, I am going to try.

I will high light a few things if you dont mind.

Exhaust is very bad smelling. Rich. Suspect MAF.

First off, plz stop clearing the codes, you will always get a p1000. ford is like that. Do you know how to check a MAF sensor with your scanner danner?


I see you have a launch, quite the capable tool, I must say. https://www.scannerdanner.com/chapt...r-testing/20-dirty-maf-sensor-case-study.html

Thank you.

I did none of the work previous work before getting the van delivered to me.

(Seems like I always get these after somebody else tried to fix it jobs)

Yesterday I recleaned the MAF just to start with.

I intend to check vacuum, and fuel pressure and check that #5 plug hole for coolant.

YES it takes open ( not WOT but part throttle and ) to get it to restart after it dies.
BUT IT STARTS right up and runs when cold.

Also, it will idle when warmed up but very rough though.

There were only two codes when it showed up to me P1000, not ready ano P1288 CHT, right now there is only the P1000 and no mil on.
Nick I checked out scanner Danner for sure.

I will get more readings this week

Thank you

CHT. Probably cylinder head temp sensor,

Yeah, the idle air control valve is the silver thing you wrote about, try cleaning that also, and do a idle air control relearn.

Here is how to do that.

 

[jigfeett]

that is interesting,
I'm not sure if I'll get out to work on this one this week.

 

[jigfeett]

CHT. Probably cylinder head temp sensor, YES it is.

 

[jigfeett]

No luck on getting out to work on this one but I will post information as I get to it.

 

[nickb2]

plz keep, us posted, I am super swamped, but for you jig feet, will go extra mile cuz your a nice guy and dont BS.

plz dont forget it is mom day, so if she dead or alive, say hello anyway. wink nods. sons come from somewhere. hint

 

[jigfeett]

Thank you, I might have time to revisit this soon but I went out and got a few screen shots.
I monitored the IAC and also unplugged it while engine was running.

The engine died immediately when I unplugged the IAC and I had to hold part throttle to get the engine to restart.

I notice IAC % was 65.62% at idle, I think this is high
I noticed MAF was at 93.493 lb/h @ 936rpm

I guess at this point I need to start fresh...with a good known set of pids to monitor.
