2004 bug engine surging


The issue may be the EGR valve. Sometimes the valve can test out OK with a vacuum pump but can still cause issues with surging. Is this happening between a quarter and half throttle? The reason you wont notice it before it warms up is because the ECM doesnt activate the EGR valve when it is cold. One temporary test you could do is unplug the EGR valve and try and drive the car once it is warmed up. If this stops the surging this is the issue. One other issue could be your Fuel pressure regulator. Your fuel pressure could be low from this and it will cause your fuel injectors not to be able to vaporizefuel as much causing the bucking feeling. Keep me posted. If you found this solution helpful please rate it when you get a chance.

Troubleshooting a 1992 buick skylark engine surges


If it is surging up and down, then i would say that it is a bad oxygen sensor, or a leaking intake gasket. Hope this helps.

Engine surge during warm up.


Try changing your PCV valve make sure the hose is clean and not full of oil. Also check the elbow end that goes to the intake they tend to collapse from oil saturation. Hope this helps.

Engine surges when cold - Once it warms up it runs fine


If carburated, I would suspect a sticking choke, making the fuel mix way too rich.
