Occasional hiccup at idle
Hi, New member with a new addition to the garage.
1998 Z28, A/T. 140K Miles, No engine mods, just getting it back to a clean setup.
The issue is when the car is idling in PARK I noticed a light hiccup or 'thump' feeling occasionally while the car is sitting in idle. I have searched various words to the describe the feeling of this as there is no associated sound with the event that occurs every few seconds. I can only describe it as a feeling of a very short, momentary hesitation. Any guidance as to what would cause this ?
