Where does the smog tube connect to the engine on an 87 ford bronco XLT. It has a 302 5.0 ltr engine same thing as 351

[MegaMarshal]

Yea, by it not being there!

[makingsnsux]

Is it possible to check if an EGR valve if it isn't even in a car?

@makingsnsux

Yes. Lift up the bonnet and look.

i have a 96 Nissan Atlma GXE and this worked for me! Thanks for posting this video and making the novice mechanic a little smarter.

I dont recommand replacing or cleaning an E.G.R valve on GM 4.3 engines, espcially the ones on astros and safaris , it is pain in the butt

[stgrenade64]

so, would disconnecting vacuume hose disables the egr completely?

What else should I do to disable this EGR completely? I need more HorsePower!

[anderson5908]

what the hell is "detonation" it sounds like something way more intense then i think it is

[weasel884]

@anderson5908 its a really annoying knock/rattling sound at a certain throttle potion, the louder it is the worse it is. you'll know if you have it because it will drive you nuts.

When the engine "begins to stumble" Should the vaccum drop on the gauge drop back to 0?

[Mattc4787]

I should have also noted it does hold the 10psi with the engine off.
