Whats up honda fam

Recently i swapped a 2000 b16a2 w 90k into
My 1996 civic ex coupe
Been having idle issues i checked everything to even buying a new iacv and sensor
Been running on a stock ecu because b16 ecus are obd2b 96-98 civics are obd2a
Fuel pressure is at 38
Few bolt ons that i put
Ive checked every possible thing
Including tps throttle etc..
Runs okay it also has LSD which i found weird


Until i get off the highway, or pause at a red light
It drops to 800 then jumps to 1800rpms.. then it stops after a few times
Sometimes it stays high


Recently I've tried doing a burnout but it seems as if i lose power

I went to auto zone to check my cel and a code
P1337 popped up for
Crankshaft position sensor
Checked to see where it was located.
And the wire was cut off...
So my question is how the car even start without the sensor being plugged in?
Could that be the problems to my idle issues as well?
I was trying to find in the harness where cqn i plug in the sensor but no solution..
Ive tried googling and reading forums but it gives me no answer..

Thank yall for your time and patience, xo

 

You're using a P2P ECU?

P1337 is a CKF sensor circuit code.

 

You're using the wrong ECU for the engine, and you're wondering why it doesn't run right? ECUs aren't "one size fits all". You can use an OBD2A to OBD2B adapter and use the correct OEM ECU, or you can use an OBD2A to OBD1 adapter, and use a chipped ECU of your choice.

Your CKF sensor wires are very obviously hanging there doing **** all. Wire the sensor properly, and plug it into the harness. It's a 2 pin connector down there, blu/red wht/red if memory serves correctly. You had to unplug it to remove the old engine. Get the proper ECU. Get rid of that aftermarket FPR, and get a stock unit. It also looks like you have an uncapped port on the back of your intake manifold - cap that.

 

Genius you are, makes sense.
Port is capped, looks open because the tube curves down.
The only port i see is a three pin or such. Sometime said that is an o2 sensor. I can't find another loose port to plug in my ckf sensor
I need to look harder probably, i tried googling to see where is the ckf sensor on the harness but no leads

 

P2P ecu yes

 

I have the correct ecu as well but again, does not fit harness and i need the adapter you said... can you send a link my way?

 

Get the proper ECU first.

 

By the numbers again, I guess. First off, you're looking in the wrong place. Second off, your O2 sensor is a 4 pin plug. Third off, this is why you label things when you unplug them. It's a 2 pin plug, coming out of the harness where it wraps around the back of your engine. Given the state of the CKF on the motor, though, you're probably going to need to either buy a new connector to pin in, or just buy a new sensor with the connector already pinned to it properly.

As for the adapter harness, Let me google that for you

 

If you found a 3 pin plug near the CKF sensor plug in area on your engine harness, then you are using a SOHC engine harness. You will need to change the 3 pin connector to a 2 pin connector and then repair/replace the CKF sensor wiring itself and plug in the sensor. Also, it appears that you are missing the lower bolt from the alternator bracket... replace that to reduce future problems.

As for the ECU... fix this issue first. You cannot expect the engine to run correctly without the correct ECU. You have 3 options to properly run the car... and I will list them from BEST to WORST for you.

1) OBD-1 ECU with a tuneable solution... like Hondata. This provides a way to optimize the components that you have with this engine, and will NOT require the repair of the CKF sensor. You will need an adapter harness to convert the ECU plugs from OBD-2A -> OBD-1.

2) It will be a hard search, but you can find a '96-97 Del Sol DOHC VTEC ECU and you will have a plug-n-play solution. (I found one for sale in 3 minutes by searching)

3) Use the '99-00 Civic Si ECU. You will need an OBD-2A ->-OBD-2B adapter harness. Depending on your set-up, you may still have emissions related codes present when using this ECU. Repair those if necessary.

 

Is this what im looking for? Its a 2 pin, rear of the motor, under my intake manifold

 

Can i get a p28, chip it?

 

It appears to be the correct plug... identifying the wire colors would verify it. It may only have two wires in it, but the middle (3rd) pin location would be empty.

Yes, you can get a chipped P28 ECU with a B16A map and an adapter harness... and assuming the bap is what you need, then it should run relatively well. Also, if you choose this route, you will not need to repair the CKF sensor because the P28 ECU doesn't use it.

 

My mistake, it has 3 wires that plug... yes i have a 96-98 civic ex coupe harness
