Here is my update regarding my issues. i checked for the fuel leaks around cold start valve and ICV. they all seem fine and i cleaned them a little. i havent noticed any difference.
right now i am suspecting the issue could be because of spark plugs and wires... one of the wires has been fixed with some silicon. i guess it shouldnt be like that right? also it could have wrong plugs too. as far as i know if you put resisted plugs it could cause little hard start and some rough running...
also i think my kickdown switch is far gone. when i apply full throttle the car hesitates and doesnt want to go. i got the code fore it with the blink code reader too. so i think that should be it i dont have anything else coming up in my mind so if you have any other suggestions i would be so happy. thank you very much
