My car is giving a code 43 but it has new coil pack. Any ideas on this.

Thanks.

 

This is the knock sensor not working or intermittently working. The most common problem found with this is a bad connection between the actual knock sensor and the pigtail connection to it. These are located in the coolant drain at the lower part of the block.

Well I reconnected the pigtail and I can't seem at the moment to recreate the check engine light coming on. I will over the next few days on see how it goes.
