Airflow sensors
The amount of air entering your engine is a mesaurable value.
This undertaken either by a moving vane air sensor or more commonly a MAF or mass airflow unit.
The early MAFs were literally a heated wire,the amount of air was detected by the level of current needed to maintain the wires temperature.
All a bit hit and miss and prone to a lot of failures. Todays MAFs use thin film technology giving far quicker responses to changing air flow conditions

Full basic health check
how well is your engine running?
good bad,hard to start either hot or cold.
Starting issues are often the sign of deeper issues developing,way before your engine fault light appears.In fact it may never illuminate and still the car will strand you.
A basic check is via the exhaust using a pulse sensor,and no bonnet lifting even needed

fuel filters
Fuel filters are a vital part for regular maintenance.
A clogged or partially clogged wil put a lot of strain on your fuel pimp causing it to fail.
for a few pounds it is false economy not to simply replace it .....dont skimp

fuel caps and evap
Todays engine have fuel tanks that vent back into the engine itself rather than to atmosphere.
In earlier day the vent was simply hung out of the fuel tank to equalise pressure.
vehicles today have a closed system that partly absorbs metro; vapour and balances atmospheric pressure through a charcoal canister.
The amount of gases or vapour drawn through the canister is dependant on many things obviously balancing atmospheric pressure with out overichening fuel mixture.
Blocked charcoal canisters and leaky pipes or non operative evap valves are the common failures.
Any issue with the evap can cause issue with engine power and need looking at.
If when you release your fuel cap there is a n intake of air you definately have issues even without a code or light appearing

Lunar autos methods
Here at the workshop a car arrives,usually with issues that other garages have long given up on.Not to say they cant fix it but its simply not worth their while pushing any further work.
In some cases a recalcitrant issue does end up in the scrap yard before its time.
All engine running issues,take time to pin down,its rarely the same day find it and fix it that isnt the real world.

No codes
No codes!
Actually no codes is the usual case of many or in many driveability issues.
Live date is mostly the first port of call then other non intrusive methods.in particular relative compression testing.
Its a simple but powerful test of an engines compression needing no dismantling of anything save stopping the engine starting

collapsed CAT
A catalytic converter is a very reliable item but they can collapse causing some major issues a quick of engine vacuum is a sure fire way of checking

Its all in the exhaust
Your exhaust seems to be nice constant stream,seems to be.In fact there are rises and falls in that apparently constant stream
How do you detect them?
You need a signal generator and an oscilloscope which can detect very short time periods,ie 2 milliseconds,it a great diagnostic tool without even lifting the bonnet.
