I was checking the code's on my car and i have 2 new code's code 43 and code 44. code 43 is esc, and code is 44 is lean at the oxygen sensor. i bought a new esc the other day for a 350 and a new knock sensor. But when i went to change the new knock sensor i couldent get the old one out and when i took the connector off of the knock sensor it just fell compleatly apart. will not having the knock sensor plugged up cause the esc code since they work together

 

Is any body going to take a stab at this one
