I swapped my valver covers today which required me to remove the manifold and what not. Newyas I went to fire up after a while so the sealant can dry, and the car started and idle'd around 1.5k for like 30 seconds then it just died and it wouldn't start back up for nothing!! I was thinkin I was out of gas but I put some in and it started for 3 seconds or so then just died again.. I'm stumped!
