Check the throttle cable isn't frayed or sticking. If the throttle isn't shut the ecu won't fire the spark.
sure ?
that's very intresting and good to know, because I'd played around with throttle position sensor (I was in doubt that a faulty sensor was the problem of my idling problems)
I'd installed it to 10% when closed (value from S&S ProTune) , what from my understanding was the default value.
Thanks , I will check that soon !
