Hey guys, I'm having a lot of trouble all of a sudden with my trucks idle. It used to idle just fine all day at 500 rpm with timing 18 before TDC. Had he timing a little closer to tdc but it would bog down under WOT so i found that this timing worked the best. Out of no where after changing the oil yesterday, the thing will not idle below 1000 rpm, it will sputter and die. I cannot seem to locate the issue. I have not made any adjustments to the timing and or idle mixture screws.

t's a small block with an edelbrock 600. Anyone have any insight into this issue?
