After you clean an engine with hot water spray, it seems to stall; when it doesn't stall, it's idling noisily. Technician A says to check for loose bolts on the flex plate near the torque converter. Technician B says to wipe down the spark plug wires and the distributor cap. Who is correct? A. Technician A B. Both Technicians A and B C. Technician B

Option (A) is the correct answer.

Explanation:

When an engine is cleaned by cold water, it accumulates over the spark plug wire and which makes the engine starts to stalls.

While when an engine is cleaned by hot water it doesn't accumulate over spark plug wire and hence does not stalls but it can make some noise.

Hence according to the scenario, the most appropriate answer is option (A).
