Yeah, I am grumpy-assed today. As Steve Martin says "WELL EXCUUUUUUSE ME!"
Nobody bothers to read the OP's comment posted VERBATIM below. The quotes are mine...
"I know about SeaFoam, but am wondering about other brands and offerings"
I tried SEA FOAM and it DID NOT WORK to cure surging, stalling, hesitation, and BAD gas mileage. Four cans, four times in a row. Wasted my money.
After another 2 weeks of putting up with a cranky Mitsubishi V-6 I added one bottle of CHEVRON TECHRON FUEL INJECTOR CLEANER and the problem vanished and STAYED AWAY for more than a thousand miles.
So that is IMHO as an ALTERNATIVE to SEA FOAM
