Im working on a 90 crx with a ZC motor in it it started throwing codes
15,17 and the car was dying just randomly while driving. We reset the ecu and now it is not throwing any codes (light no flashing) but the same thing is happening anyone know whats up? also where is the port to hook up a scan tool?

thnx

 

88-91 Civic ECU Trouble Codes


With the ignition on the ECU will display a single flashing light
indicating the system is operating. When the ecu sets a trouble
code, the check engine light will come on and the ecu stores the
code in the memory. The trouble code will remain in the memory
until voltage to the ecu is disconnected. Removing the hazard
fuse in the main fuse panel for 10 seconds will reset all trouble
codes. Reset the memory after repairs are made. Make sure the
ignition is OFF when disconnecting the main fuse.
Code System
Code 1 (1 flash) Oxygen content
Code 3 or 5 Manifold absolute pressure
Code 4 (4 flashes) Crank angle sensor
Code 6 (6 flashes) Coolant temperature
Code 7 (7 flashes) Throttle angle
Code 8 (8 flashes) TDC position (top dead center) timing
Code 9 (9 flashes) No. 1 cylinder position (1.6L)
Code 10 (10 flashes) Intake air temperature
Code 12(12 flashes) No code 11 don't know why. Exhaust gas recirculation system
Code 13 (13 flashes) Atmospheric pressure
Code 14 (14 flashes) Electronic air control (EACV)
Code 15 (15 flashes) Ignition output signal
Code 16 (16 flashes) Fuel injector
Code 17 (17flashes) Vehicle speed sensor
Code 19 (19 flashes) No code 18 for some reason Lock up control solenoid valve
Code 20 (20 flashes) Electric Load

 

1st make sure you are getting a spark on all cylinders. Perhaps your cap and rotor may need to be replaced. Also you might want to check all of the fuel injectors. There is a small metal clip that holds them in place (located on the wire harness). If this is missing on one of them it may cause your car to idle different speeds and even stall. The main purpose of these clips is to hold the wire harness to the fuel injector itself. This is just a quick troubleshoot. I hope it can help solve your problem.

 

ok thnx since this isnt my car i dont know
but what do your cross to get plugs,wires cap,rotor for the ZC?
a local shop said 86-87 integra 1.6 is that right?

 

I bought Bosch Platnium +4 plugs (about $6 each), cap ($17) and rotor (can't remember how much but cheap) for 89 integra (1st generation). Also 89 integra plug wires should work. Everything from my experience for the ZC is 88-89, 1.6 DOHC acura integra. I know from experience that some 89 integra parts will work. My ZC was also maufactured in 1990.

alright thnx maybe we will try those.

the plug wires on the nuber 2 and 4 cyl are very VERY lose they just sit there while the other too are real snug like they should be.

 

well ok i think i have one of the problems on this figured out it seems this smart fellow decided to use 3 of jiffy lubes fuel system cleaner
at one time and his plugs were fouled out. i put new plugs and wires on yesterday and tonite the new plugs from yesterday are fouled out.
were also throwing a code "1"were gonna run the car to bone dry to try and get the fuel **** out and ill replace the plugs and the o2 sensor
any thing else you guys think of please post.
