1990 325iX, 241k, newer cat.

Could a bad coolant temp sensor cause my car to fail emissions? HC 706 CO 0.45 @ 773 RPMs

Work done so far: valve adjustment and new valve cover gasket, new fpr old one leaked, wires, cap, plugs, rotor.

Could the O2 sensor cause this?

Please help.

Yes it can. There are other possibilities
