Why does my car feel like its surging?

Why does my car run rough when it warms up?
A Wonky fuel pressure regulator can cause rough idle when warm. Once warm, a bad fuel pressure regulator can cause a rough idle by leaning out the mixture due to low fuel pressure.
Why does my car surge when cold?
Symptoms of a bad intake air temperature sensor that can cause a rough idle when cold is the engine stalling, the engine surging, the hard starting, the excessive fuel consumption, and the stumble and jerking while accelerating.
What happens when your car is surging?
Surging is associated with a sudden increase in speed that occurs while trying to maintain a constant one.

What causes an engine surge in a car?
Step 4 – Some vehicles are equipped with an inline fuel filter, when this filter become plugged it lowers fuel delivery creating an engine surge. Learn more Step 5 – If a vacuum line has caused a leak the engine will surge, as vacuum lines age they can become brittle and fall off the engine or accessory. Learn more
What happens to car cooling system in hot weather?
Cooling systems rely on coolant/antifreeze to keep all parts of the engine cool. On a hot day, this liquid runs around the engine at a higher temperature, causing some parts of the engine to overheat and fail.
Why is my car surging at idle speed?
When an engine’s computer can “hunt” or “surge” at cruising or idle speeds it is searching for program compliance, there is a problem elsewhere in the system.
What does it mean when your car is surging?
Engine surging is when an engine starts easily and accelerates smoothly, however after a few minutes at a steady speed, it either surges in speed or misfires. Misfiring happens when one of the cylinders of an engine’s combustion cycle fails. Since an engine has four cylinders, the car would still run if one cylinder fails.
