b16y7 from 97 DX in my 93 cx hatch problems

I have just dropped a d16y7 into my 93 hatch (d15b8)... It started fine, ran good, then started surging (UUUMMMMMBBAAAAAA-UUUMMMMBBAAAA) So I killed it and checked the radiator and needed to add some fluid... Added the fluid and now it wont start????? It turns over good, and sounds like its getting both fuel and fire, but it spits and pops and backfires like the timing is off. Any help would be welcomed! Thanks Josh

 

bleed out your coolant at the thermostat housing and check your vacuum and map censor,then post what happened afterwards. rep me up if this fixes your problem....lol

 

Hey thanks for the help... I changed the plugs and it started right up, and I ended up having a crack in the hose of my pcv valve. It starts runs and drives well now. Thanks for Everything!
