idk ill have to check i have disconnected the battery and then reconnect let it run it runs fine idles fine no check engine light just idles at 1100 rpm and slow to come down under driving conditions. with all my other cars there was a screw to adjust the idle on the actual throttle piece but this one is like just a boltlike fixed and i did all new gaskets when i put it on? and i capped that little valve buy the sensor because the breather from the valve cover was short and wouldnt fit?
