Hey guys, so I have an automatic 95 hatch, with 41,000 origional miles, engine blew last friday (still investigating it) so my boy Danny and I dropped in a new D15B7 engine, it runs great, but is misfiring from 1500-2000 RPM.

The engine has my old intake manifold ( from an auto D16Z6) and D15b7 everything else.

From reading other posts it sounds like this is from my IACV, Im not throwing a CEL, but the idle is really really weird, it will either be near stalling out, or 1500 RPM.

If I just replace my IACV, am I good to go?

 

Also, its safe to drive it around like this right? Not going to mess anything up

 

probably your dizzy/cap/plugs or plug wires.

 

it would misfire more than just that rpm though? everything else i have read says its IACV

 

bump?

 

Start here^. Also check the ignition timing with a timing gun.

The IACV would not cause your engine to misfire.
