Hey Scotty, thank you for the time you devote to helping us out. My brother and I, switched out the head gaskets on the engine for his car - a 2003 Eclipse GT 3.0L V6. We did the job because the car left him stranded on the interstate and the radiator had a milk-like substance (oil mixed with water). Anyway, we cleaned everything in the engine compartment to make sure we could spot leaks after the rebuild, we got new vacuum hoses, new spark plugs and wires, and did a really good job overall ... but the car won't stay on. We have now set the timing twice at the T and rechecked the two camshaft positions to make sure they were perfectly aligned with the timing marks on the valve covers. When we turn the key, the car will rev up to about 3000 RPMs then rapidly go down, sputter, and then stall (about 4 seconds), unless, we press the gas pedal. By pressing the gas pedal, we can hold the engine at different rpm ranges for as long as we want. It did not have this issue before the rebuild, did we do something wrong? PS, we have completed similar builds before (at least 12 times) and have not had this issue with any of them.
