Hi
I have a 95 accord ex 5 speed, we did a swap from f22 obd1, tiger japan sent me an h22 obd2 motor by mistake. Our issue is that the car bucks really bad when you drive. It has the vtec code and the code for the itac i think. i have seen in other posts about the ecu. Any help would be appreciated. Also it seems that on the obd2 the egr is not used or when we hook it up the car dies, when it is unhooked it idles like it should.

 

It's their fault not yours. Tell them to fix it on their dime.

 

What ECU are you using?

The VTEC wiring and the IACV wiring is the same, check the wiring make sure the connections are clean and good and tight and that there is good continuity between the sensor/switch and the ECU.

As for the EGR, when hooked up through the proper vacuum system it should not be open at idle. If you are using an OBD1 P13 you will need to swap the wires at ECU pins A11 & A6. If your EGR is hooked up to A11 (O2 heater power) it will be sending out a constant battery voltage. Therefore the EGR will always be open at startup.
