the symptons include very poor acceleration, poor engine performance, and also the engine coil packs tend to blow up quite often and the oxygen sensor will need replacing.
Bad idle, hesitation on acceleration, DEcreased performance and gas mileage.

A faulty air flow meter can lead to incorrect readings of the air entering the engine, causing an improper air-fuel mixture. This can result in poor engine performance, reduced fuel efficiency, increased emissions, and potential engine stalling. Additionally, it may trigger the check engine light, indicating that the vehicle needs diagnostic attention. Overall, a malfunctioning air flow meter can significantly affect a vehicle's drivability and longevity.
If your 1990 Infiniti Q45 won't start due to a faulty air flow meter, it’s likely affecting the engine's ability to receive the correct air-fuel mixture for combustion. You should first confirm that the air flow meter is indeed the problem, possibly by checking for any error codes or performing a visual inspection. If it's confirmed, replacing the air flow meter should restore proper airflow and allow the engine to start. Additionally, ensure that all related sensors and connections are functioning properly to avoid future issues.

Weak fuel pump? Bad fuel filter? Bad air filter? Plugged catalytic converter? I had the same problem with my Corsa, changing my mass air flow meter fixed it!!
What will a bad mass air flow sensor cause? Mass Air flow sensor regulates amount of air coming in to the amount of fuel being used. If this sensor is bad you would have either a overly rich or lean fuel condition. Check the fuel pump as mass air flow sensor has no moving parts and rarely goes out.
When the mass air flow sensor is bad you will have a rich smell in you car. Additionally, your car will consume more gas as you drive it.
Seal leaks oil... Or oil in your charge air cooler...

Symptoms of a bad pressure tank include fluctuating water pressure, short cycling of the pump, air sputtering from faucets, and waterlogged tank noises.
thermostat could be bad, or location of it, air flow over it.
