agb1980 10 Posted October 3, 2013 Hi guys, im sat by side of road waiting for AA (again) Car missfires occasionally and then cut out yesterday on A1. Wouldn't restart till half hour later then drove to garage who replaced crank sensor. Car was running better but now cut out again. Any ideas where to look next? Cheers Quote Share this post Link to post Share on other sites
agb1980 10 Posted October 3, 2013 got started again after 30mins and got back home. Just checked with vagcom and got no error codes. As said above there has been an occasional missfire (like a split second jolt} usually when the engine is under load. Any advice would b really appreciated :) thks, Andy (car is a 95 vr6) Quote Share this post Link to post Share on other sites
Jon_vr6 1 Posted October 3, 2013 Check HT leads, coil pack/dizzy cap for splits for the occasional misfire as the the cutting out usual culprits are the ISV but that usually causes the car to stall but start again straight away. Always worth using the search bar at the top of page (eg stalling vr6) as im sure people have had this problem before Quote Share this post Link to post Share on other sites

robrado974 1 Posted October 3, 2013 As above , out of interest why did the garage replace the crank sensor ? Quote Share this post Link to post Share on other sites
seanl82 23 Posted October 3, 2013 Its quite a common symptom of a crank sensor fault tbf. Cutting out and unable to start when hot, but will start again once cooled. Usually due to cracked insulation at the elbow. Quote Share this post Link to post Share on other sites
agb1980 10 Posted October 3, 2013 Thks for replies, garage said they pulled a fault code for the sensor. Will check the coilpack- could it be ignition/ ecu/ immobiliser? Any way to check? Quote Share this post Link to post Share on other sites
robrado974 1 Posted October 3, 2013 Crank sensor will show as a fault if the engine is not running , while it's hooked up to the vagcom . Quote Share this post Link to post Share on other sites
