Seafoam

[Ace85]

Does Seafoam work well? I have an ‘85 305 4 bl with 66,000 miles. My engine is sputters when I give it gas, but idles smooth when in park.

if you give it gas while in park does it sputter or run smoothly?
can the assumption be made that yours is all original and you are running a Qjet? that would make it 40 yrs old and probably due for a rebuild due to dried-out seals and internal leaking plugs or wornout power valves.

seafoam is a great product , but it's not Magic .

was the car stored for the last winter or longer ? did it run well before ?
