The check engine light came on and vehicle began to run roughly and stall, the vehicle was inspected and dealer found negative temperature signals, consumer has experienced problems on six occasions where the engine would stall and run rough, and has had various componets replaced, such as radiator coolant, coolant sensor, fuel pump, sending unit assembly, distributor, fuel injectors, spark plugs, wires, serpentine belt, throttle-positioning sensor, egr and oxygen sensor, the bracket that protects the main wire harness was never installed from the factory and consumer feels this was the problem to begin with, some of the componets were even replaced a second time and still did not resolve the problem.
