Hello H-T

I have a 1990 Honda Civic EX with a B20V swap.

I converted the car to obd1 by using a dizzy jumper, ECU jumper, p06 converted to p28 obd1 ECU. However im running obd0 injector with a resistor box.

The car starts up fine idle fine but has a CEL code 9 (CYP, cylinder NO.1 position). When i get off 1st gear it lags before going. Also when im already rolling and accelerate from a constant speed it will lag before going.

I researched a little bit and a lot of people said that it is the dizzy.

so far i tried:
- Another dizzy
- Another ECU
- Another set of spark plug wires

No luck.

I researched it some more and some people said you can bypass the sensor by hooking the CYP to the CKF on the ecu jumper.

I have tried this technique and it still throw a CEL code 9.

I am going to pick up some new spark plugs tomorrow and see if that would fix it. Any help is appreciated.

IF YOU HAVE NOTHING NICE TO SAY THEN DONT BOTHER POSTING!!

 

bump.

 

friend of mine had this problem. i think it had something to do with wiring going into the ecu. he was obd2 to obd1 tho.

 

jumper was bad when he bought it?

 

so i tried replacing the spark plugs and still no luck.. im not sure what else can be the problem.

please help!

 

bump for help!

 

 

thank you. will try this out.
