Hello, I’m not sure if this is the right place to post it or if someone posted something like this already. Okay, so I have a 1990 camaro iroc z with a 5.0 tpi I recently purchased. I changed out the Injectors yesterday. Ran fine all day. Now I wanted to start it and it would start but sounded like it was misfiring badly with smoke coming out of the exhaust pipe. I did the paperclip trick to read the codes. I have the 43- knock sensor error and 53 codes. I’m going to attempt to change out the knock sensor. Does anybody know where the location of the knock sensor is? Any help would gladly be appreciated! Or point me to the right direction

 

Coolant temp sensor may be going/gone bad.
The flooded idle will show these codes. Mine never showed a CTS code.
Good luck!
