Hi everyone. So I have a 2003 Kia Rio with about 125000 miles on, living in northern Illinois. Over the past 3 months or so after heavy rain my kia has a really rough start. The car shakes as if youre going over a speed bump or if you have been in se Asia driving on the gravel/dirt roads. The engine bay looks moist and I think that might be the problem, something getting wet? I let it run/warm up a bit and then shut it off. After 10 mins or so I start it back up and its fine. Just wondering if anyone has had this problem or any ideas on how to fix it. When warming up, it shakes as described until I rev it to a little over 1k and then it feels normal until the rpms go back down. Thanks in advance!
