Max Capacity Posted December 7, 2012 Share Posted December 7, 2012 Try a can of seafoam in the gas tank or B12, that was talked about the other day, It may help clean the injectors. You can even suck some in through the small hose on the BOV. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
