Problem solved: Wiring harness was bad, now cats are bad

I meant, do the resistance check with the car cool to see if you get a different reading as opposed to the hot reading.

Oh. Well the o2 sensors check out ok on both hot and cold, haven't tried the injectors.
Drove into work (it's 72* at 6am), and it took a little longer for the CEL to come on and the symptoms to exibit themselves.

*crickets* Anyone? Does this sound like a fuel pump issue?

Lupo came over last night and said it's most likely wiring. So, I'll be buying a harness here shortly. He also called my tranny "acceptable".

Well, the car has gone from bad to worse. Dying at every stoplight, feels like it's running on 3 cylinders, etc, etc, etc....basically undrivable. Took off the intake and the fuel injector rails today and tested all the injectors, all went *click* *click* *click* so I presume they are good. Went through the wiring harness and saw a few bare spots. 1 on the knock sensor connection, 1 on the ground that bolts in the valley of the motor (the ground itself looked rusted over), and 3 on the injector connectors. Pulled a few plugs from the front, while light, they aren't terrible, but compared to the rears, they look like daylight. Checked the coolant levels, everything is fine, and it's bright green. Coolant overflow is also bright green. I'm not losing any coolant, and there is not oil in the coolant...as I said, it's bright green...and there is no coolant in the oil (trying to rule out headgasket since my parents Chevy Blazer just blew both of them with 110k on the motor). A wiring harness is on the way (thanks Rich aka SHOBlu), so wish me luck in getting the beast back on the road!

I guess no one reads this .

Any luck with the new wiring harness?

Harness should be here Wednesday. Some people are suggesting the computer is bad. Replaced with another, and the issues are the same....but that's not to say the other computer I have is good. I'm without a vehicle until I get this figured out.

Harness is in! Only took about 3 hours (I'm a stud). I had a few broken temp sensor connectors, knock sensor only had 1 of the 2 wires on the connector, a few things were frayed and open...it was in bad shape. So I go to button everything up, and I end up pinching a vacuum line and tearing it . So close! Should have her up and going by the weekend though!!!
