    No VANOS readings in INPA for s50b32?

    Hi, my car is missing a lot of low end torque. I recently had a similar problem, except that the idle was terrible too and was loud, it turned out to be the exhaust vanos solenoid's wiring was loose so i soldered it back and the car was running great again. Recently it has lost a lot of low end torque, it still pulls ok, not like when the exhaust vanos wire was loose but it's still missing a lot. Also it will misfire and bog a little while part throttle.

    I tried the carsoft but it didnt give much info except for the codes, so i decided to try inpa. I verified a couple stuff were working like the TPS, but i couldnt see any vanos readings.
    It only said Digital, Analog1, and Analog2, im using the carsoft cable btw, with the carsoft attached as well, (the serial is going from the carsoft to the laptop with inpa on it)
    any ideas? could another software show the vanos readings or do a diagnostics of the vanos?

    i wonder if it's the mass air flow sensor. At first it didnt show the code, after driving it showed it, then i reset the codes and tried driving around again, but it didnt appear, i only have an oil level sensor code which i think is due to it not installed right (i recently had to change the oil pan) but i dont think that affects the engine does it? thanks
