We just finished a ZC swap in an 89 Dx hatch. The car idles ok but only revs to 3000 rpm and then starts to bog down. We used an ECU from an 88-89 Integra. It is flashing codes 4,5,10,15. I belive they are crank sensor,map sensor, and EACV sensor codes.Also does anyone have a layout of the vacuum lines? We may have some crossed. Any help would be appreciated.
Thanks,

PM ZC_CRX, he just finished that swap in a 91 DX this weekend. He'll help ya trouble shoot.

 

Thanks,I'll do that.

 

Check all of your sensors. You may have some of them pluged into the wrong place. The TPS and EACV plugs are too short and they must be extended. Also be sure to switch green/white and yellow/white wires on TPS.
