This maybe the problem. If you used an oil impregnaged air filter you may have oil on the mass air flow sensor thin filiment wire. This will cause the engine to idle badly. Remove the mass air flow sensor and you will see 2 really thin wires. Now you can go to the store and some auto parts places sell spray to clean the wires. I would use brake clean non clorinated!!!! do not spray full force but just a little and let dry completely. This is very common with oil impregnated filters. Ford does recommend that you do not use such air filters on mass air flow vehicles.
That probably means you are running lean, I would check for a vacuum leak somewhere (hoses etc) If you had the heads of recently check that. Make sure the intake manifolds look okay.
Probably just a leaking intake gasket. When it's surging, try pressing downward (with most of your bodyweight) on the intake. If it settles out you need to replace the intake gasket.
Hormone surges.
if surges worse at idle when cold possible intake manifold gaskets leaking will usually set o2 or fuel trim codes
Billy Surges is 5' 11".

The different between sag and surges
No, I do not physically install devices. However, whole house surge protectors are typically installed at the electrical panel by a qualified electrician to protect your home's electrical system from power surges.
it cant protect the system against power surges
no they are bad!
No, tornadoes do not produce waves or storm surges. Tornadoes are violent rotating columns of air that typically occur over land and do not form over bodies of water like oceans or seas where waves or storm surges are generated.
A: YES it can to a point but as speed of surges increases the capacitor will start to behave like a coil
