I just saw that Advance Auto now carries a spray version of Seafoam. Supposedly you spray it into the throttle body while the engine is running. I was wondering if it is worth a try.

Probably an alternative to sucking seafoam in through a vacuum hose. I'm not sure either seafoam ever cleans the injectors, unless added to fuel, and I don't know how you're going to effectively add an aerosol to your gas tank.

Seafoam is not snake oil. It cleaned the crapola out of my new-to-me 244. I literally had 2 tablespoons of soot fall out my tailpipe and the car runs about 10 times better than it did. It may not make a difference to well-maintained cars, but for dirty mcnasty cars, it may make a huge difference.

Injectors cannot posssibly be cleaned by spraying anything into the throttle body. Whatever the stuff is (probably just a solvent) it will not come near the injectors. At best it may make the inside throat of the throttle body shine a bit, not sure what benefit that would be.

Are you trying to fix a problem or is this a preventive thing?

snake oil in new aerosol form...

If it needs to be maintained, repaired or replaced on a 1990 240, I've probably done it. '90 240DL, 290K looking forward to 300K badge (or sticker??). >>You haven't really worked on a car until you draw blood<< :-}

Seafoam works in only two forms... lubricating hinges and schit AND spraying into combustion chambers if you plan to store a vehicle for more than, say... forever? Which you're not, so view it as just a messy version of silicon spray (which spray isn't?)

If you wanna clean the intake area just pull the intake and replace the manifold gasket, TB gasket, get new seals on the FI's, Clean/Replace the Flame trap tubes.
My favorite is to take the manifold to the DIY car wash and blast every inch of it. While you're at it soak the duct-work (bellows for you older guys) in some "Go-Jo water" and air-blast them dry (or leave them in the sun for an hour)
Spray that Seafoam into the Idle Air Valve.
Bust the gunk out of the Flame trap.
My trick to the TPS is to grind notches into the mounting flange edges to make a perfect re-match during install.
Check your vacuum and enjoy the extra 2-5mph you get... if not, you will have eliminated 85% of your potential vacuum leaks.
Order the parts, you're in an old car that probably needs them.

I have read bad things about this stuff, I wouldn't use it until I heard from someone that thinks it is a good idea.

Probably not. It just sounds like a bad idea.
