Any cel? Have you tried a chipped ecu with a basemap for the b20?

jdmson43

No ecu jus stock i thought about it but i was thinkin its the iacv behind the intake mainfoldbut it started doin it when swap the b20

jdmson43

Yes there is exceleration but when you lead off that when it falls down and wants to die but if its warmed up it will die so other words there is no hesitation when you: excelerate

Warm up your car and unplug your IACV. If your idle does not drop or the car does not die then it's a faulty IACV.

So I did what you told me to do and it died I'm stuck I ran out of ideas I think it might be the ecu because of the map but I could be wrong,

jdmson43

ok still havin the same problem if anybody has any ideas on what it would be feel free to tell me

I have the same set up 95 integra gs n I recently swapped in the b20z. With my stock ecu.
1st.. did the problem start happening asoon as u did the swap or did it happen a few days,weeks after the swap?.
2. Are u sure all grounds and connections are clean and secure?
3.did u reinstall the spacer on the fuel rail when u replaced the fuel injectors? Is the fuel filter good?not all clogged up n ****
4.is all u timing set correctly??firing order etc?r u off a tooth on ur valve timing??spark plugs gapped correctly?wires cap rotor in good shape?
5.check ur vaccum lines and pcv system...a restricted line is never good.
Also if u rev duz ur car feel sluggish??

once again.. where u located i can find the problem for u for as little as 20 bucks if u are close by... and i guarantee that if u fix whatever it is i find it will fix ur issue.
