Any who, HummerZ had shown in the ported throttle body thread about these products and his H3 running glass smooth. Hoping he'll give a tutorial on how he goes about achieving this. My H3 has been less than smoot the last few months. And yes I've cleaned all the usual suspects over the years and ran chemicals in gas and through engine lol. Just would like to pick up any other tricks or tips that might help.

 

 

Where does the seafoam spray get used?

 

 

Walmart sent me a FREE can of Super Tech Motor Treatment to try. Comparable to Seafoam at a lower price. I will test it with my next induction.

 

Wow, half the cost, Hopefully no half as good, I will be interested to see how well it does!

 

Scanner=P0300 Engine Misfire Detected!

Back in '12 when I purchase my 3 it was throwing the P0300 ONLY when idling during warm up. I've corrected the PO neglect!
I let my 3 idle today outside @35°F ambient for an hour still idles Smooth NO CODE!

 

Seafoam has really treated me well through out the years. I now only buy it in the gallon container so I can control the concentration ratio better plus its much cheaper then buying the little bottles.

 

Not much cheaper> 8 PINT CANS=1 GALLON. Make sure to keep the can sealed airtight to prevent evaporation.
I use Seafoam for induction cleaning and only use 1- 16oz pint can when I perform the service.
I also add LUCAS in the tank, This is DEFINITELY BUY THE GALLON=>FOR HUGE SAVINGS!Lucas Oil 10013 Fuel Treatment Gallon

 

I have had the p0303 error for many years and replacing coils and spark plugs does not help. What did you do to make the error go away?
