did your wiring harness get rubbed at all, like in the drivers side wheel well? If your harness is messed up like shitty wiring or wires that are showing the copper, you could be getting codes like this as well

 

The service manual states.....to test the wiring, all you need to do is test for continuity between the harness and chassis ground. I performed this test and didnt have any problems.







I noticed two of the harnesses that go to the ECU (inside teh car) are the same. I think it would run really crapp if i had those two switched around right?

 

You can check the injectors by hooking up a fuel pressure guage to the fuel rail or fuel line shrader valve. Turn on the ignition to allow the fuel pump to pressurize the line. Turn off the ignition and observe the fuel pressure. If it drops off rapidly then an injector is not closed.

Thanks for the tip. I would have figured that. Normally you can find out if you have ANY fuel leak that way. YOu'd think if you had an injector leaking like that, that the motor would have a real hard time starting, true?

 

OK you could check for any leak that way.

You would bleed all the fuel that is pressurized through the injector that is stuck open.

Yes, it could be hard to start.

Could be a bad O2 sensor, check the o2 cross counts. If the difference low to high is not great, you could have a rich idle condition. The Fuel pressure could be higher than stock, that would cause rich idle for sure.

Will the 02 sensor throw a code if its readings are skewed?

It probably won't unless the sensor was damaged.

New question



If the 02 sensor wirign is damaged slightly, and the ecu isnt seeing it, is it possible that its throwing the knock sensor code as well? I noticed on the wiring diagram that the knock sensor and the o2 sensor both operate off of the same ground wire. If one connection is damaged, it should be possible for the other two as well
