plenum spacer trouble

so I just installed a skunk2 Plenum spacer and during warm start ups,
it will turn over but hesitates a little.
like it will flow smooth, then dip then flow smooth agin.
Im thinking vacuum leak, but idk i cant look at it till tomrrow.

make sure all the bolts are tight and make sure the rubber peice that goes around the filler neck for the oil isnt stuck between the spacer and plenum

when installing spacer make sure you tighten the outside bolts first before you even touch bolts in the middle.

If you tighten middle bolts first it will warp your plenum and prevent it from sealing tightly all around.

So just loosen up all the bolts, tighten up outside bolts first (properly) and then just lightly tighten middle ones.

Did you disconnect the neg battery connection when you did it? Even if you did though, the idle control could get out of wack. You should do the procedures to reset the throttle body... this is on the last page of:
http://www.motordyneengineering.com/manual.pdf

I know it's a skunk, but the same procedure applies and the motordyne instructions were most handy to me since I just did the spacer install last weekend.

Torque wrenches are your friend. they are a very very valuable tool to have.

torque wrench is not going to help if you tighten inside bolts first

^not bad. Lol I got it for a steal so I couldnt pass it up. But I do like it.

I think any spacer will do, so look for a used one

you funny.

its not like you buying a used oil filter or anything. Spacer is just a piece of aluminum, there is no such thing as "used spacer" there is only "tested and proven to be in proper working condition" spacer
