Quick question; I've always experienced this since I started using this (08) motor, but want to make sure this is normal... (stock ECU BTW)
Every time I switch on the run switch, at the same time the fuel pump primes, the stepper motor for the secondary throttle shaft actuates, jamming against the full closed position. It jars against that for a short while, then stops. It's done this every time I've turned it on. I'm just wondering if it's normal; it sounds like crap!
The motor does run, or at least has till I ran it out of fuel (hoping it's just being a royal PITA to prime again - have verified I do still have spark, but not getting much in the way of fumes out the tailpipe)...
I don't have a stock dash to pull codes with, but haven't needed it yet and hoping to eventually get away from this ECU so don't really want to invest in such...
