A technician is diagnosing a car that lacks power during acceleration. There are no DTCs, and a check of the ignition and fuel system does not reveal any problems. Technician A says the exhaust system should be checked for a restriction. Technician B says the stator overrunning clutch inside the torque converter could be slipping. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Both Technician A and Technician B are correct. A restriction in the exhaust system can cause a lack of power during acceleration due to back pressure that prevents the engine from expelling exhaust gases efficiently. Similarly, if the stator overrunning clutch inside the torque converter is slipping, it can also lead to a lack of power because the torque converter cannot efficiently transfer power from the engine to the transmission.
