1985

[Paul Tholey]

Hey Bruce,
        I was just out with my friend in his 1985 Pontiac TA.  It has a cold
start problem, and there is a slight hesitation when the trottle is applied.
Kinda like a car without the accelarator pump working on the carb.  The car
has 150,000 on it, mods are a Hypertech chip, and a 3 inch Flowmaster cat
back kit.  I found codes 12(self diagnostics?) 34, 54, 12 again.

Any input?  I also will be calling about the burner, again.  TIA

Paul
