I got a B16A put in my 90 Civic about a couple of weeks ago. I thought everything was cool, no problems. Then I come to find out that when I push on the gas the car will hesitate, then kind of jump into Vtec. I dont know what the problem would be?? I have had all of the gaskets replaced except the head gasket (which I know wouldnt cause that problem) I have replaced almost everything that youre suppose to when doing a swap. I was think it was maybe the CPU. Anybody have any ideas on what it could be??

 

Are you throwing any codes?

 

what obd, what ecu, what year motor.

 

The car isnt throwing any codes. I think that it is OBD0, it is running the stock computer that came with the swap. I think the CPU is a PR3. The motor is a 90.
