I asked this earlier but now I have more info. I have a 1985 Cadillac fleetwood with a 4.1 v8, digital fuel injection. When ever I try to drive up an incline, the slightest bit of gas causes the car to pop and sputter and occasionally die, but it fires right back up. Other than on hills, the car rides and drives great. My fiancé followed me home and said I have a single exhaust, but I appeared to have dual, because exhaust was coming out both sides. This makes me question the catalytic converter. Is that a possible diagnosis?
 
Yes the catalytic converter is likely. I had a similar issue which turned out to be as simple as a faulty fuel pump which in turn affected other various parts. This was on my 1953 Willys Overland
