im pretty sure that the throttle position switch works if my car slows down at WOT but picks up if i let off the gas.

i did some testing today on the CIS and here are the results

duty cycle @ idle: ~50%
duty cycle @ 2500rpm: ~70%

O2 @ WOT: ~ 0.200v

all signs which point to the fact that my engine is probably unning a little lean at WOT.

the O2 sensor definitely works just fine. When I am at WOT, the sensor reads close to a constant 0.2v, and when I let off a tiny bit and feel the surge, the O2 sensor voltage starts jumping around again.

q: the engine is supposed to goto an open loop mode during WOT correct? is that why the voltages arent jumping around and my car goes slow?
