95 Legacy L Random loss of Power

[Matthew352]

95 Legacy L Wagon

Ill be driving and then randomly there will be a loss of power. My pedal will be on the floor and the rpms will drop and then after a short while *5 seconds or so* itll kick back up to where it was before it dropped usually 4,000 rpm.

But if i pull over and shut the car off... Smokes come pummeling out from teh underside of the motor.

there is no noticable place of fluid loss and all my fluid levels are good.

There is not Audio noise, no backfire.

THERE IS NO CEL and When i run the SCAN Tool there is also no codes.

Car Idles at about .750 rpms theres no fluxuation in rpms at idle.

So far i have...

-new Fuel Filter

-Cleaned Maf Sensor

-Airfilter

-Plugs and Wires are newish and working as should

any suggestions on what to check next??

the whole no CEL or code thing is getting me.. i am by far not a mechanic just a poor parts changer with youtube.

 

Car has 118,000 miles if thats helpful

 

ANY HELP WILL BE GREATLY APPRECIATED!!!

Undo the various electrical grounds in the engine bay, clean them and put back. Also, check that the three big multi pin connectors on the top right of the engine where it joins the bell housing are firmly connected.

after trying everything under the sun we finally figured it out. Had to disconnect the battery and idle sync procedure *not sure if thats the techinical name* literally disconneted the battery and did something for 15 minutes and its running perfectly fine....
