What causes surging engine?
If an engine is not getting enough fuel (this is called “running lean”), due to fuel pressure (regulated by the fuel pump and regulator), restricted fuel injectors, a vacuum leak or really anything that throws off the fuel mixture going in to the engine, this can cause the surge.
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.
What should I do if my engine is surging?
Check and adjust, ignition timing. Ignition system problem causing a, weak spark. So, if your engine has a distributor; check and replace distributor cap, rotor, ignition wires and spark plugs. And, you should also have the coil packs checked. Furthermore, there may be a fault in the computerized engine control system.
Why is my engine surging at low rpm?
The fuel pressure regulator may be operating at, low pressure. Check fuel pressure with a fuel pressure gauge. Replace fuel pressure regulator. Your ignition timing may be set incorrectly. Check and adjust, ignition timing. Ignition system problem causing a, weak spark.
How to fix engine surging, stall, misfire?
This is such a simple fix that causes such a large inconvenience. 1. Remove Plenum and spark plug wire cover (10mm socket) 2. Start vehicle 3. Lightly miss wires with water 4. Replace old wires with new no matter how healthy they appear. Loading…
There may be a fault in the computerized engine control system. Check engine control systems with a scan tool. Have a mechanic test the circuits and repair or replace components as required, since this is generally not a DIY job. The fuel filter may be partially clogged. This is an easy fix! The fix: Replace the fuel filter.

What should I do if I have an engine problem?
The fix: Check and replace vacuum lines as required. Possible internal engine problems. The fix: Check compression to determine engine condition. EGR valve may be stuck open. The fix: Replace EGR valve. Drive axles may be loose or worn. The fix: Check and replace CV/universal joints as required. The fuel injectors may be dirty.
