Two technicians are discussing the testing of a catalytic converter. Technician A says that a vacuum gauge can be used and observed to see if the vacuum drops with the engine at 2500 RPM for 30 seconds. Technician B says that a pressure gauge can be used to check for backpressure. The following technician is correct:
Restricted exhaust flow is caused due to overheating of the catalytic converter. To measure the exhaust system, back pressure a pressure gauge is inserted into the oxygen sensor's bore in the exhaust. Hence they are both correct
They will be travelling slower than 10mph. if they were travelling at the same speed then they would stay an equal distance apart. if they were travelling fatser then they would be getting further away more quickly than Bobby is catching up. maybe they are travelling at 5mph but I'd say it's a safer option to chose under 10mph
