4KQ A/C problems

[Mark Kingsbury]

Hey there,

	I have converted my 85 4KQ A/C to 134A and I'm having some problems.  If I
start the car cold (say after sitting all night) and turn on the A/C, it
blows cold real well, no matter if I'm in stop and go traffic, highway,
whatever.  But as soon as I turn off the car after its been warmed up and
then get back in before allowing the car to cool down completely (like
overnight), the A/C no longer blows cold.  Since the "cool" line runs past
the exhaust manifold, am I getting some sort of heat soaking into the system
not allowing it to cool properly or what? Not enough refrigerant? Any ideas?

Thanks,

Mark Kingsbury
