ok I recently changed the head gasket on my 93 honda civic I took the head in and got it pressure tested and milled. it came back good I got new gaskets and put it all back together when I started it, it had a really bad idle and when I give it gas it will die I have no idea what to do or what could be wrong any help would be awesome thanks in advance guys

 

That is similar to what has happened to me when I swapped my manifold, except my idle isn't bad, not too long after I tried various different things pertaining to fuel, amount of air flow, my crank position sensor threw a code, so my plans are to replace that, make sure the timing is correct and go from there. I think my timing is off (not sure how I managed that without a distributor...).
