Hey I have a 89 CRX HF with a D16z6 in it. I bought this car for my 15 year old son. We have put a new motor in this thing and it runs the same as the old one that had hardly no compression. The problem I am having is it seems to idle ok but will not take the throttle at all. When you throttle it up it pops and very erratic....It has a stock everything in the motor we went threw it...p28 computer, it was in the car when we bought it. I have triple checked timing and all that's good. I am new to Hondas but not to car in general. I have been turning wrenches for almost 25 years....and I sure don't know anything about the swaps other than what I have read. I wouldn't be doing the swap at all if we didn't buy the car with it already done. The peeps we bought the car from jack legged it and I have repaired the wiring using both the 89 and the 93 wiring schematic. Any ideas from anyone would be greatly appreciated. Thanks DDEAN50

 

Uncalibrated throttle position sensor possibly.
Are there and cel?

 

well, if i remember correctly.. the hf was DPFI(Dual Point Fuel Injection) and the d16z6 is a MPFI(Multi Point).. if they didnt wire it up correctly thats a major issue...

 

DoeS It POp Right Away Or Does It Do It After It Rubs For A Little But
