Hey Guy's

New at this forum but not new in the Honda world.

I have swap a b18c4 engine to My 1997 del sol and now i have big problems.

I dont have any idle and the engine's runs and hack on 1500rpm. And i think the engine's goes pretty good otherwise. Maybe not 100% good but it goes to drive.


But here is the strange problem. When i pump the brake i get the idle to 600-700 rpm. And when i take off the vaccum line to the brake servo the cars go up to 1500 rpm in idle and "hack" / goes bad there.


I have try other maps sensor, tps, electric signals.


I did have obd2a in My d16y8 engine and have now a converter from that to obd1 p28 ECU.

I run on the b18c4 Europa loom



What can the problem was

 

If the brake pedal is effecting idle then I would check the brake booster for a vacuum leak.

 

A SOHC ECU running a DOHC engine....

I don't think any loom/wire harness is going to fix that.

I believe you need a P72 for B series motors.
