Engine restoring liquid.

That Sea Foam engine cleaner does wonders on a + 126,000 mile Nissan. Elimaneted light load surge, got rid of a 4 mph hunting in the cruise control. Milage is almost as good as when new. ANND. The exhaust smells wonderfull. Maybe a shotglass of it will help my exhaust!

 

Hmm... a miracle-bottle that works? That would be something. Must be one darn potent cleaner. Perhaps the old Plymouth could use a shot or 10...

 

OMC engine tuner worked extremely well. I don't know about tuning, but it will wash a lot of carbon build up out (and down the driveway )

Way back - before you lads were born - a short cut for decoking engines was to warm up, then pour a teaspoonful of brake fluid into the carburetor.
Don't have anyone standing near the exhaust when you do it - the fallout from Chernoble is nothing by comparison.
But BE WARNED - we only did this on cast-iron blocks. Can't be held responsible for the modern alloy jobs.
