jm1300busa,
Race fuel will clean your injectors but with a street map for pump gas the MR12 will give you a lean condition, it is also very expensive fuel system cleaner.
I would suggest our Wynn's Power Charge: http://prostores2.carrierzone.com/servlet/brockracing/-strse-2832/Fuel-System-Treatment/Detail
Works great, less expensive, no lean condition worries. Drain fuel, add 2 Gallons of fresh pump gas and can of Wynns, run through system. |
