I use SeaFoam Motor Treatment, I use a aquarium air valve and vinyl tubing and insert it at the Fuel pressure regulator hose attachment to the throttle body. The valve is to meter it in slowly.

It produces Smoke out the wazoo. 90's are Cabbies, Cabby, or Cabriolets, Cabrio is a totally different car... (I know I am anal that way.).

Grab the end of the hose and pull it off the throttle body.

There's many obstacles? is it as simple as removing the silver band? or? sorry noob here first time doing this

On the back side of the throttle (passenger side) you will see a vacuum hose that goes down to a gold anodized device, that is the Fuel pressure Regulator.



It is the Clear hose in the Picture at the back of the throttle body Pull it off the nipple of the throttle body. Insert your hose there, then into the Seafoam can. Or you can Spray Carb cleaner in that hole too. You will have to slightly increase the rpm, and have your car half out of your garage as you will be killing tons of Mosquito's throughout your neighborhood.

You will also find out if your exhaust manifold is cracked.. as more smoke will come out the manifold than the tail pipe.

Thanks for the photo explanation i also meant if I wanted to clean the intake manifold on the 90 cabby - there are way to many things attached/

I shows you how to remove most of the crap to change a valve cover gasket.
