Thanks for choosing Just Answer . I'm Wolfgang here to help!!
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.

i do need more info from you .. first what year is your caddy and second was there any fault codes stored or check engine light?

please let me know

there is an adaptation needed with the factory scan tool to reset ecm values to*****test. the ecu learns of how the system is working and fine tune it . once it gets to the extreme it sets a code and then needs to be repaired and then reset values and then recheck
