Ok so i am still working on this 5S (Project PAIN in my ass :) ) There is an odd problem im having here that i need some help figuring out: 1) When i turn the engine over the car will start very fast...and die right off the bat... 2) When giving it a bit of gas then turning it on the engine will run but stumble like its miss firing. As soon as gas is let off then engine stumbles then dies. 3) I hooked up a Vac gauge to one of the spare ports on the intake mani and did #2 again
