also, how hard is to change the thing because its way back of the intake, thanks guys

 

I beleive I paid around $60 but its cheaper from gmpartsdirect.com. Get an inspection mirror and look back there. There are two nuts that hold it on. Make sure you use the right size wrench to get them off, you dont want to strip these. I thought they were 13mm but mine were 1/2 inch. You may need to take off the EGR solenoid to get good access to one of the nuts. Only one nut holding the solenoid on and you can get it off with a socket. Remember how the vacuum lines go together when you take them off. Also make sure you get a new gasket.

 

cost is around 60-80 dollars....I use Craftman's ratching wrench to remove and install..... Its tight but it can be done..... If you remove the fuel rails its alittle easier...

 

i have one for sale that was working fine when i took it off my 1995 car. make an offer through PM.

 

Got one from Jason Cromer last July for about 40 ish..

 

It,s not bad at all, just have to reach way back in there and you will have to work by feel. I took mine off because of LT install it was pretty simple actually.
