well my "mechanic" re - installed different gaskets and the other intake, and says its still doing it( idles jumping ) .. he is saying its something to do with the short block thats making the intake not seal correctly. If they machined the block from the 78 blazer when matching it with the 91 tbi heads and they did something wrong is there any way that would cause the intake not to seal or it to appear to have a leak in the intake right back at the passenger side rear corner under the egr area? he says I have to sign something saying he doesnt have to fix it again and now he wants 100 ? trying to find out if I need a new or different short block or a different mechanic.. when not at idle it runs great
