207legacygt Posted October 6, 2019 Share Posted October 6, 2019 My legacy every now and then will almost completely die out at idle but then at other times idles completely fine. I thought vacuum leak but couldn't find any leaks. I dont know what else it could be? Link to comment Share on other sites More sharing options...
Max Capacity Posted October 6, 2019 Share Posted October 6, 2019 Have the small black O-rings between the Intake manifold and the TGV's been replaced with the larger orange one's ? You can see them with a good light. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Warlock Posted October 7, 2019 Share Posted October 7, 2019 Are you on stock cams? Do you have a boost gauge? If so, what is your vacuum at idle? Do you have access to an OBD reader that can liew live data? If so, what does your long term and short term fuel trims look like? Might be abbreviated LTFT and STFT.

Max Capacity Posted October 7, 2019 Share Posted October 7, 2019 black? I thought they were always orangeish brownish? Yes, when I had issues back in 2010 I think it was. I removed the black ones which were much smaller then the orange ones. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).
