I've had the too rich/too lean codes for a couple of weeks now. They were happening before the new catalytic converter and down pipe.

I have had 3 different, used, fuel pressure regulators in the car.
I have had 2 different, used, oxygen sensors. (one with only 37,000 miles on it).
I have had 2 different air mass meters (used, but good).
I have swapped on a used Volvo brand air intake hose from the AMM to the throttle body.
I have a new rotor, new plug wires, new ignition coil wire (Volvo brand).
I've cleaned the throttle body and installed a new throttle body gasket.
I've cleaned the idle air control valve.
I've checked the fuses and spun them around.
Got a new battery in there too.

I pulled an engine temperature sensor from the junk yard on Sunday. So maybe I'll put that in to see if it makes any difference.

Maybe I'll go back to the junk yard and pull an ECU. How much does one of those run at Crazy Rays junk yard?

Car still for sale if anyone wants it.
Within the past two years it's got all these new parts.

1. Radiator (Volvo).
2. Steering rack.
3. Front struts.
4. Strut mounts (Volvo).
5. Battery.
6. Strut tower brace.
7. Catalytic converter.
8. Front down pipe.
9. Replaced auto transmission with good one.
10. Rear main seal.
11. Rear trailing arm bushings (Volvo).
12. B cam.
13. Flame trap.
14. Front brake pads and rotors.
15. IPD sport springs in the rear.
16. Thule roof rack with fairing.
17. Some tires.
18. Head gasket.

So you can see it's decent, but the thing isn't running right, throws codes, I'm sick of it.

Have a spare T cam and the original M cam.
Have some front IPD sport springs too.
Plus a good passenger side front fender that is rust free. Just needs to be painted to match the car.

Art, let me know if you have some time this weekend and I'll drive up to your place so you can check it out.
