Hi,

Car is a 1996 Honda Accord Ex
2.2L vtec, auto trans.

Just got done putting a motor in the car, which was a JDM OBD1 motor. Rewired the sensor locations to the OBD1 dizzy and the car runs fine.
New plugs, cleaned out the EGR already


The problem:
Once the car is up to highway speed/anything above 65, it trips the CEL with p0301,0302,0303,0304, and p1300. All which are cylinder misfires.

 

How did you wire the dizzy? Colors? Check your plug wires, cap, and rotor. Also try another dizzy if you can get a hold of one. You also need to test your injectors one by one.

 

This is how it's wired up:
OBD1__________OBD2
White/Blue: Red (front of engine)
Orange/Blue: Green (front of engine)
White: Black (distributor)
Orange: Yellow (distributor)
Light Blue/Yellow: White(front of engine)
Light Blue/Green: Blue (front of engine)
Yellow/Green: Yellow/Green (distributor)
Black/Yellow: Black/Yellow (distributor)
Blue: Blue (distributor)

Info I got:
Here's some OBD1 distributor wiring information from a 1994 Helms manual:

White/Blue: Top Dead Center sensor ground; ECU pin B14
Orange/Blue: Top Dead Center sensor signal; ECU pin B13
White: Cylinder Position sensor ground; ECU pin B12
Orange: Cylinder Position sensor signal; ECU pin B11
Light Blue/Yellow: Crankshaft Position sensor ground; ECU pin B16
Light Blue/Green: Crankshaft Position sensor signal; ECU pin B15
Yellow/Green: Ignition Output signal; ECU pin A21
Black/Yellow: Battery Power via coil primary positive to Ignition Control Module
Green: coil primary negative to Ignition Control Module
Blue: Engine Speed Output(RPM); goes to Tachometer, Cruise Control, and Automatic Transmission Control Module

If you have an internal coil distributor, the green wire will be internal from the coil primary negative to the Ignition Control Module.

Here's some OBD2 wiring information from a 1996 Helms manual:

Connector at front of engine:
Red: Top Dead Center sensor ground; ECU pin C13
Green: Top Dead Center sensor signal; ECU pin C3
White: Crankshaft Position sensor ground; ECU pin C12
Blue: Crankshaft Position sensor signal; ECU pin C2

Connectors at distributor:
Black: Cylinder Position sensor ground; ECU pin C14
Yellow: Cylinder Position sensor signal; ECU pin C4
Yellow/Green: Ignition Output signal; ECU pin A20
Black/Yellow: Battery Power via coil primary positive to Ignition Control Module
Blue: Engine Speed Output(RPM); goes to Tachometer


I will have to check the cap and rotor, but the car starts, runs fine, idles right. Just pops the code on once at highway speeds. And how do I go about check the injectors? I am using the ones that came with the motor, and can still get ahold of the my original ones if necessary.
