Couple of issues with recent swap. FPR??
I have a 1990 Civic rt4wd wagon and I had swapped in the d15z1 motor from the 92-95 Civic Vx.
I am not getting any check engine lights, I did everything myself (conversion harness obdo-obd1). This is not even close to being my first swap but these are a few problems I am not too familiar with.
1:
First off is the oil pressure light staying on until for about 5-10 seconds after I have started the car (longer the usual thats for sure). But after I let the car run for a bit it goes away and never comes back. Something that I had caught my eye when I was doing the swap was the accumulation of oil near the oil pump (not fresh oil just old crusty oil thats been there for awhile).
Now before you immediately start saying bearings this and that, when I picked up the motor it didn't come with an oil pressure sensor on the back of the black so I put one in from the d16a6 (or one I had laying around). So maybe its just some of the gasket sealant is partially blocking it (or plumbers tape)??
2:
Second of all when I accelerate it seems to drive fine EXCEPT when I let off the gas (throttle) and it starts decelerating and then try to re-accelerate it will stutter a bit. It lead me to believe the ignition coil was going bad or it needed a tune up.. so I switched them both out, only to go from a major stutter to a minor stutter (helped some but not fully).
Is it possibly the fuel pressure regulator? I am running the stock d16a6 FPR.
3.
Lastly when I shut off the car after driving it for a bit and then try to restart it it (even if the Main Relay clicks correctly) it will start up and then die of slowly unless I give it some gas.
which leads me to think it could possibly be the fpr again.
On another note the fpr worked fine on the d16a6 motor.
And I know my wiring is good, I'm not a newb at wiring.
Thanks,
Shane

Re: Couple of issues with recent swap. FPR??
you might want to try to source the fpr for at least a d15b7, if not the z1, it might be running too rich and when decelling it's dumping too much fuel in for a min. not sure, but i think that could the your problem
