Ever since I added a cai on my car, my car rpms go up and down violently when the car is somewhat hot. For example: I turn on the car ( cold start ) and it acts fine. But let say I leave it for 2 hours after driving and then turn it on again, then thats when the rpms go up and down, then after a couple seconds it goes back down to regular idle. I have been having this problem for months.. Oh, and one more thing.. Whenever I go uphill my car starts to hesitate. Like i'm over here pressing on the gas but it doesn't wanna add that power to make it up hill, i forcefully have to press it to go. All of this has been happening ever since I added a cai. Another thing I also noticed is whenever I get my car up to 35-45 mph it starts making a whistling sound for a couple of seconds then goes away, but when I let go of the gas it goes away.. and then it comes back after I stop and go again. Has anyone had these problems?
