Hey Everyone,
My car has developed a strange engine shudder that occurs only between the temps of 35-40F. It happens when the car is still warming up, when I pull up to a red light and put my foot on the brake pedal the front end makes a vibrating/shuddering noise. You can only hear it from the inside, it sounds like something under the hood or maybe dash is vibrating.
If I shift into neutral or park it goes away. It looks like the RPM drops in drive, but it won't happen when the car is warmed up or if its colder (20F) or warmer out (45F). I recently installed a front strut bar, but I'm not sure it's responsible for causing the vibration I'm hearing.
I checked the oil level this morning, it's right at the full mark. I might try some injector cleaner but it's worth noting Hyundai recommends frequent spark plug replacement in these engines. I believe the manual states to change the spark plugs at 45K, more frequently if the car idles or is driven at slow speeds. I've also seen the 2011 manual indicate to change the plugs out at 22.5K.
Any ideas?
-Thanks
