How prone are the knock sensors to failing? At this point I literally have everything in the engine bay out except the engine itself and brake master cylinder and resevoir. I'm wondering if I should replace them with it this disconnected. I took it all apart for the complete cooling system overhaul. I got the car over the winter and it had a hunting issue with the idle. It would be normal then idle really low start shaking in some cases and also stall out in some cases. If it didn't still out then the idle would go back up eventually and then minutes later the cycle would start all over again. As long as there was load on the engine it was fine but at lights or stopped otherwise would do that. I noticed the vacuum hoses were all shot today especially the fuel injector tree.
