Hi guys, I'm in the process of doing maintenence on my 97 5th Gen and some things are bothering me. recently I feel that my lude is not giving me all the performance its supposed to. Here are the facts:

97 Lude 180k KM (about 130k miles)
Completely stock except for intake
Changed:
Plugs a couple of months ago (they are clean)
Battery
TPS (TPS readings perfect, 10% on idle)
Rotor and Cap + Wires

Tested engine compression:
215-212-200-210
I consider this VERY good for 130k miles on it

On the scanner I'm getting 1.25v for the #1 O2 sensor contstant (idle). It will sometime change when WOT. Is the constant 1.25v normal?

2nd O2 sensor gives (on idle) 1-1.1v

We tested while driving and in 3rd doing 35-40mph (60km/h) the scanner says 30% engine load. That normal?

The only thing i can see is exhaust or headers? I still have the original ones (as far as i can see since I bought the car 2 years ago) Of course theres rust and exhaust pretty used. The exhaust still seems to travel though it "normally". Cant see headers because I syill have Heat shield on.

Any Ideas?

 

 

Ok, Thanks a lot for the graph. As I can see I should be getting about .5v for both O2 sensors? How is it possible to get 1.25! I have no check engine at all...
Sorry for all the questions but i'm not THAT technical, learning though the process though....

 

Bump, anyone else?

 

Can someone tell me what the voltage of O2 Sensor #1 should have at idle when cold? hot?
Thanks
