fuel/air woes

[MEDIK418]

Not knowing squat about blown engines I have to rely on the written word but everything I've been reading on fuel pressure lately says you are in the "zone" at 38. Even so, what you describe is much like the problems we were having prior to installing a new fuel pump on the 89. Rich conditions would generally cause an engine to run really well when cold and get worse as it warmed up. What you are describing gets better after warmup making me think it is running too lean. I'd be real interested to see what cures the problem as the boys are planning blowers for both cars in the next few months.
