Problems With 01

Star scan,never heard of it good to know. As far as it doing it,it stays that way all the time. And fuel pressure is good,Airdog 100 at 14psi.
 
Lets keep the same thread going JL. This way we don't get off track.

Have you cleaned the MAP sensor yet?
 
Everything that has been tryed. New injectors, new apps, new cam sensor,new cross over tubes and orings, mapp sensor cleaned, ait sensor cleaned,new fuel filters,battery post cleaned, grounds cleaned.:bang

Has never thrown a code, scanner hooked twice last week, nothing.
 
it sounds like something is wrong with the pump or idle control. have you checked the TPS voltage?????? If i am correct the pump does all the idle control internal. If you want i have a spare pump i could loan you just long enough to see if that fixes it.
 
don't trust the key trick to read all the codes, when i get a CEL it's usually just the 1693 that shows up but when i scan it with a real scanner there is alot more involved.
 
When you say pump I guess you mean VP44,and the idle control is in side the vp44? apps voltage is good, it is new.
 
Both the APPS and the internal timing of the pump control idle function VIA the ECM.

If the ECM gets a bogus validation signal from either then it will idle wrong or have a flat acceleration issue.

One question when you installed the APPS how was this done?
 
It is a Timbom apps.I hate to take this think to the shop it is going to kill me on parts and labor. I wont to put a vp44 in it but at the same time that may not be what it is with the ECM coming into play.

Check for error codes if you have P0121, P0122, P0123 then the APPs sensor is shot. Just replace it. Don't bother try to PHYISCALLY calibrate it. You can try the battery disconnect method.
 
Like i said i have a used pump that you can throw on there along with a ecm for an 01 auto. Ill be more than happy to let you try them both out. If you want i have a couple of buddies there in elgin and in Mcdade that can help you throw the stuff on.
 
That sounds good man thank you for the offer. The only problem is mine is a standard.I dont think the standard and auto will swap will they,then I need the ecm flashed.
 
I have an 02 HO 6spd ecm and it should work as I swapped it out for a 01 5spd on my old truck with no issues. I can reflash it to a 01' 5 spd.
 
Hey I willing to try it if your willing to offer, thanks.I guess you know where my shop is. I will be out all day Friday and thru the week end but my helper should be there late Fri.& Sat. And I will be there Monday in and out. Maybe we can catch up later.
Thanks Joe
