Help me with explorer..Please

[sasquatchpa]

I am a GM/Jeep CJ-5 guy. So my son brings home a 98 Explorer...AAArgh!! It seems to have a huge vacuum leak, but no sucking sound? Is there a valve I should look for? should I just pull and replace all vac lines?




P.S....I tho't about titling this "Dora doesn't ****"

It is solved, fixed, and on the road!

Was any work recently done around the intake?

Whoops...V8 or V6?

Is it giving a lean code for both banks? If so, look for a cracked elbow on the pass side rear by the throttle body IIRC. VERY commmon problem.

Check this...

The pcv valve hose is notorious for splitting open. Near the firewall, very hard to see. The house will feel soft and gummy

^^^ explorerforum.com like brownbagg says, those guys will help you out.

otherwise, when that 4.0 starts howling at you from the intake pipe replace the IACV..

Check the brake booster for internal leaks

First suggestion would be a tall cliff! Second would be al the great experience here on the GJ. Try the explorer forums for how-to write ups and pics. My brother has the same explorer I have worked on some. I am impressed with time those guys spend on how to guides, etc.
I will say with a basic set of rebuilt heads, a $100 U pull it ****** three years ago, and some shocks, that thing is running strong for 250k miles.

Explorer forum nailed it !!!!!!!


It was the idle vacuum valve, an easy fix if you have pics!1


Thanks all around

Seriously, though, check the pcv valve hose. If it isn't bad now, it will be soon.
