2000 Expedition 4.6

[Billme]

Today, it done good.. This one is going to be a hat puller..

I had a heart issue, so I’m on a monitor.. The next time I started the engine, it done it again..Since I was concerned about higher voltage going to the pcm, I isolated the alternator totally, and it still done it, so I’m going to order the PCM..If it does it after that, I don’t know what I will do

Ok, I need some input..I waited for this cold snap, and was able to pull connection off the ICV, and due to the colder air, it was able to idle.. Still got the pulse..So this should eliminate the computer, Right?
What has baffled me is no lean codes, and how smooth, but does show some lean tendencies sometimes..
Since it’s worse, and takes an hour of running to settle down somewhat, I’m convinced there is a crack somewhere..
I’m going to go ahead and start replacing the whole intake.. Should have done it in the beginning..
Since I have a frankinengine, lol, I’m not sure what to order.. Mainly concerned about these new intakes, and for non PI heads
I’m draining the coolant today

 

[Billme]

Well I chickened out, I got to think about all those smoke test.. So I ordered the computer.. I haven’t replaced it yet.. I had to put everything aside due to health issues, but as soon as I can, it will be done..

Well folks, I finally got the Expedition fixed.. I changed out the computer, and a friend reprogrammed the keys.. He used a ICON 8 btw..
It’s running smooth and idles perfectly..
I guess this concludes this part of the redo hehe
