I checked the idle valve ma`s again tonight and I am seeing around 600 ma when cold, but then it drops off as the temps rise finally settling around 200 - 300 ma. Too low according to your article.
If I blip the throttle, the amps don`t move much, maybe 100. If I unplug the OVP while its running and plug it back in, it jumps to 600ma and drops again to the 200 - 300 ma level. I tried the old OVP and got the same results.
When I checked the duty cycle at X11 #3, I get a fixed 50.7 cycle. All temp sensors are in spec. Could this be a ECU problem?
Where to start investigating? Any way to check an ECU?
