Help!!!!!!! D15b

[mouse323]

I have a 93 EGwith a D15B, the problem is that it idles up and down when its warmed up. If the motor is cold it"ll sit just fine. What can the problem be?

Have you tried cleaning the IACV and FITV(if equipped)? Also, try unplugging the IACV when it's warmed up.

Throwing any codes?

No, it's not throwing any codes. I checked for vacuum leak and nothing. I gonna check the IAVC.

So I unplugged the IACV and it worked. Thanks.
Now my other question. Would any IACV off these engines
,D15B8, D15B7, D15B7, D15Z1, fit a D15B?

 

[K2e2vin]

B7 should be the same, not sure about the others. I can actually check since I all of those engines! lol.

 

[AHHVTEC]

the z6 should work right k2e2vin ?

 

[K2e2vin]

Yes; D15B VTEC has the exact same manifold minus the purge solenoid.

All of the D15s asked of all have the same IACV. Only difference I notice was the rear plastic color was either black or white; but uses same connector.

Alright, cool, thanks K2e2vin and AHHVTEC.
