Ok, so I have an 89 civic dx hatch. Had the original d15b2 in it with like 250k. Well i got an 0bd1 d15b8 with 120k on it, swapped all of my sensors over to it, put my dpfi intake manifold back on it, also used the dpfi dizzy and engine harness. Now it will start up, but it studders when you hit the throttle. then at idle it will just die unless you hold it there. Its not throwing any cels. there are no vaccum leaks anywhere, timing is fine, ive just about replaced every exterior gasket and hose on this motor. Can some one help me please ?

 

whats your fuel pressure?

 

timing?

 

dont know the fuel pressure, re timed it already.

 

bump anyone ?

 

Dude, mine is doing the same thing. I swapped in a d15b8 with the b2 dpfi and sensors. Mine takes forever to start and when it does it running rich and seems to miss fire. The b8 only has 130k on it. Seems like spark or fuel... the injectors

 

Any cel???

 

Yeah but how to check which cel it is?

 

my cels are 5, 8, 10, 16
