I enquired at both dealer and garage about diagnosing my car for being a bit sluggish and less peppy. Both said it usually takes one hour to find the problem\narrow it down for such a matter.
I'm just wondering what specific things typically get tested during this hour.
In my receipt it lists: Test drive, ignition, compression test I'm assuming ignition refers to spark, fuel injection and air intake.
I imagine they check air intake for any blockages, check spark plugs are delivering correct voltage spark, and fuel injectors are working. The compression test would be to check engine health. However can you break these steps down further? For example I imagine in addition to checking fuel injectors are working I imagine they would also check the fuel pump is working or if it is worn is this not possible? Timing is necessary for combustion so would they also check the state of the timing belt? With spark do they have a way to test the voltage be generated at each spark plug or do they individually test battery, ignition coil, plug wires and then inspect spark plug condition? seized brakes etc
Basically can you break down what specific things usually get tested in this hour?
