new CAI, trouble starting, hard idle, stalling

[bruceparkinson]

99 4.0,i just disconnected my battery and am going to let it sit a few... is this good . i heard i need to cuz im prolly running rich right now and the comp needs the reset. anyone done this before ?

 

[Sbyrne97]

try the battery...but most like stalling and hard idle is due to a vacuum leak somewhere check all your connections and make sure everything is tight.

actally they shorted me a breather filterin the kit i ordered. so one of my breather tubes doesnt have a filter on it at the moment. is that the cause?

 

[Sbyrne97]

you might have to be a little more specific...is the breather plugged innto the intake?

 

[bruceparkinson]

no. they were tho, now there are just small breather filters(well just one), there are no holes with adapters on the intake pipe for the tubes to connect to

 

[Sbyrne97]

thats your problem then...odds are those tubes were hooked up the the pcv system or some vacuum and is now sucking in air causing your hard start...I do not have a 4.0 so i would not know specifically where these hoses hook up or go too but you might have to modified your tube drill a hole just enough for the hose to go into or go back to your old intake...

incase your wondering what pcv is it stands for Positive Crankcase Ventilation and basically it keeps the small amount of gases that are in the crankcase from collecting...
