Sorry bout the lack of pictures, more to come later.

(i mostly circled everything in red that you should pay attention to or that needs to be removed)

Ok first things first spray everything down with pb blaster or liquid wrench about 24 hours before you try unbolting anything..

Image

Heres a number of things you unclamp / remove before you do anything

#1 Hose
#2 Fuel line
#3 hose
#4 hose
#5 fuel line
#6 hose
#7 intake
#8 Idle Air Controll (it made my life alot easier to pull the intake manifold back) but u definetly dont have to, but if you decide you want to, its only 2 bolts , 2 vacume hoses , and 1 wire w/ a housing that u unclamp.
#9 Strut bar (if you have 1)

Heres the amount of bolts you have to remove.
Image


The ''Bitch'' bolt , you will have fun with taking off / putting back on...
Heres a better picture of how many studs/nuts


Heres a picture of the ''bitch bolt'' with all of the hoses on

Image

After you'v removed all the bolts

There is going to be a mount that holds the intake manifold to the block, Be careful there are wires clamped onto that mount...
Should be 2 bolts on top, by the intake manifold side
and 1 big one on the block.


After you have removed the mount.. you will have studs sticking out, The studs will be unscrew out, They are threaded both ways and will look like this after you remove the nuts

Image

Carefully ( if your gonna re use the studs ) with vise plyers (try not to damage the threads) unscrew all the studs.. they should come out fairly easy

Slide the intake manifold back CAREFULLY,

Clean off all the old gasket material, i would also spray everything down with a little Air intake / Throttle body cleaner... **MAKE SURE EVERYTHING IS CLEAN BEFORE REASSEMBLY!** Whatever you do dont drop a bolt down into the block ! wont be fun to take out...


*ok guys did this DIY off my mind of how i did it a while back.. correct me on anything that im wrong on... , MORE PICS TO COME PROBABLY SOON..

It is unless you have something wrong with your system. Or you took off your gas cap first.

LOL


Yes, when you remove the gas cap it is to depressurize the fuel system.

That would explain the high pitched hissing I hear when I remove it lol. Does that remove fuel from ALL of the fuel lines in your bay? :?

If so, that's amazing :)
