Hi There I have a 1997 Subaru Legacy, 2.5L Sport Utility Sedan AWD. The car starts fine, and engine runs stable, but it vibrates unusually, a bit too much than a normal running engine would. when pressing gas pedal, it stops vibrating, only when idle. I was told to replace spark plugs and the wiring set for the plugs, I did, but the problem still remains. Can anyone tell me what to do next?

Re: Subaru Engine Vibration
I'd suspect a vacuum leak in the inlet manifold, check to see if any vacuum lines might have fallen off. This can cause a lean misfire at idle, but often it's not enough of a leak to make it lean enough to misfire at higher rpm. If a leak is not obvious, check if it is a leak by buying a can of engine start (or even CRC will do) and spray it all around the inlet manifold. If the idle smooths out while you're spraying then then goes rough again, it is a leak. By spraying in specific areas you can narrow down the area of the manifold or gasket that is leaking.

done at home and engine lights flashing indicates that wires for the transmission have not been connect or connected correctly
engine light also reports on transmission problems and the first cause is wiring
from there get a fault code reading to get what servo/' solenoid or sensor is faulty
if this happens while the engine is cold please run it idle once to start in the morning then drive and if it does always then. put the gear to neutral with the brakes on and push the accelerator slowly to higher side to see if engine is smooth if it shakes or shudders or engine seems to un stable use carburettor cleaner with the engine roaring say around 2000-2500 rpm. just spray from the opening intake of the air filter on top of the engine. spray two to three times, if it does not work remove the top cover of air filter remove the air filter and close the cover then try again. if it still does not help take the car to service station to check for all hydraulic oil and clutch oil. are you sure that engine oil is on top indicator or it is low. this could also be the reason and the engine could cease also.better first check for the engine oil level on the oil dipstick.usually located near the fan belts of the engine front side
Always let your vechile to reach operating temperature ,saves on wear and tear especially on them very cold mornings,Take it to your lube and maintence person and change the fluids and check for metals in the fluids you might have to replace soon,because the clutches are worn to a point of being replaced is the only option
the timing marks are on the camshaft pulleys and there are 2 notches on each pulley> they line up with 2 marks on the engine block for each pulley> and the crankshaft has a notch that lines up with a mark on the engine block aswell> pluss the new timing belt will have white marks on it that will line up with all of the marks on the pulleys when they are in the right place so its nearly impossable to do it wrong
