check for the camshaft/crankshaft sensors... where is your camshaft/crankshaft sensors
I have a 1996 cadillac deville concours, an it has 4 oxygen sensors

Should be two front and rear of engine
The 1991 Cadillac Deville oxygen sensors are located on the firewall and the air cleaner housing. The firewall oxygen sensor will be on the drivers side. The air cleaner oxygen sensor will be on the back of the air cleaner housing.
you have three oxygen sensors, 2 on the front and rear exhaust manifolds, right past where the pipes are connected together. and one by the catlyc converter good luck paul g
the four wheel bearing/hubs are speed sensors for the abs system.
It is probably your egr valve that needs replaced!
The Northstar engine uses two O2 sensors. Sensor 1 is located on a bung in the exhaust after the manifold, but before the catalytic convertor. Sensor 2 is located after the catalytic convertor. It's that simple.
