adio

I had the same symptoms in my old commodore vn 3.8 series 2. Would run fine cold, as soon as heated up was missing and generally ran like rubbish. Turned out to be a crank angle sensor, I also go that fault code. You can test if take vehicle for a drive let it warm up to get the symptoms. Park up and slowly pour cool water over the sensor, located behind the harmonic balancer. Then start up again see if it runs better, something to do with the sensor expanding when getting hot giving wrong readings. I replaced with a second hand one the first time, a year later same symptoms again. So I went new the 2nd time around. From memory wasnt that expensive new. The hardest bit was needing the correct tool to remove the harmonic balancer / pulley. Hence why the first time I went 2nd hand from a local wrecker in chch and they replaced for me took no more than 10 min for him with the tool needed. Another way to test is - From memory when you check the fault codes / jumping the pins the radiator fan goes full speed? I had to do that a few times to get back home as the radiator fan going for 5mins or so was enough to cool the sensor down and get you home !
