Lean Hot Starts
Just started seeing this problem. Cold starts are fine, Hot starts will die after 4 seconds because it's getting no fuel.
Went back to my old faithful tune which always started fine and now that does the same thing. IATs are under 80f so pretty sure not heat soaked on restart.
Also noticed ECT temps have worked their way up over the past month. Ambient is about 80-90f and ECT used to run 185-190, now running 205-210 under the same conditions.
Has to be something mechanical. Possibly melted cats?. No detected loss of power but haven't been beating on it due to heat and waiting to finish up some valve train changes
