I have a 94 grand and it is runnnig rich. 112000 miles did a full tune up plugs wires, 02 sensor. Cleaned the trotlle body. Changed the coolant and thermoasat. The car was sitting for 3 years. Just bought it So fresh gas and fuel filter. Car wont idle right sems to serge and has a hesatation when pulling off. Put my scanner on her and no codes. But I see that the coolant temp senor is closed and never opens up even fully warmed up. Does any one think I damaged it when flushing the system out. , Maybe it got air bound and baked it. It is orginal. Seems like the computer is fight it self to lean out but then stalls. Before I did the tune up it ran great start right up touch the key. I even swap a tps from the bone yard still runs bad. Thanks bb
