Idle Control / Fuel Delivery - Fuel, Air & Emission Symptoms
Common symptoms and diagnostic guides.
Car sometimes lurches at lights
Experiencing lurching or jerking when stopped at traffic lights often points to issues with idle stability. Common causes include ignition, fuel, air intake or idle control faults that disrupt smooth engine operation at idle.
Engine cuts out in slow traffic
Engine cutting out in slow traffic is usually due to idle control, fuel delivery, or electrical charging issues that prevent the engine from maintaining RPM at idle.
