Can Seafoam cause engine pinging?

And therefore possibly cause some rough running/pinging until the Seafoam has had a chance to mix with the fuel and the fuel has had a chance to run through the system. It sounds as though it might just be the Seafoam doing its job. That's a good thing.

I put in the whole bottle, I think that's what the instructions on the bottle say.
I flashed the 87 tune just to see if it changes anything. Still pinging, I will empty the tank now and hope it will be gone with new gas.

weird that it would ping at low rpms.
i had some pinging in my old mazda truck as i would have to floor it to get over this hill on the highway while maintaining a highway speed.
switched to a higher octane and the pinging resolved.

I would reduce (retard) the timing manually with your tuner until you get some fresh gas in there. Pinging at low RPM is very odd. By retarding the timing 2 or 3 degrees at say 0-2000 and 2000-4000 RPM you'll reduce the chance of doing any damage.
Once you get refilled, reload the untouched tune you were running before to get the timing back to normal. I don't remember if you can advance it otherwise as whatever change you made becomes the new '0' and you can only subtract (reduce) timing, not advance (increase) timing.

I don't have a can in front of me but IIRC an entire can may have been a bit more than what is called for 16 gallons of fuel. It's possible that your fuel mix was just a bit off; enough to cause pinging; but it's also possible that your fuel initially was borderline correct on octane.

My guess is you got a bad load of gas(been there, done that). If your latest fill up was at a Mom & Pop station, then suggest getting the next load at a station that sells top tier gas(Chevron, Exxon, Mobil, Shell, Sunoco, or Texaco).

Alright I filled it up with fresh gas and the pinging seems to be gone now.
I still think the pinging had something to do with the Seafoam because I always get gas at the same brand name gas station.
