faulty air flow meter
change ur air flow meter its on ur air box pipe
A faulty air flow meter in a electronic fuel injection vehicle will lead to drivability issues. The car will not be able to send prop fuel and air mixtures to the ECU which will lead to issues starting the vehicle as well as maintain a solid idle.
It is difficult to diagnose a problem like this via the internet, but it could be the air flow meter. A faulty air flow meter will often cause this type of symptom. Its a good place to begin the process of elimination, at least
That is usually a problem with the map sensor or air flow meter, depending on the model engine in said Supra. www.driftmotion.com
If this is the Eco Tech Vauxhall Engine then it will either be the EGR Valve (Exhaust Gas Recirculation Valve) or the Mass Air Flow Meter. It's worth disconnecting the Mass Air Flow Meter when it is reving and see if this alters the revs if not then I would suggest cleaning the EGR Valve as they get clogged up with black soot and subsequently alters the air to fuel mixture as would the Mass Air Flow!
The purpose of a flow meter is to measure the flow of either air or water. They allow one to measure the total volume of air or liquid flow and the rate of the flow.
the mass air flow sensor detects the flowing of mass air into the engine while the mass air flow meter detects the amount of mass air flowing into the ingine.
Measures the amount of air to flow past the meter in cubic feet (CFM) or meters (CMM) per minute.
where is the air flow sensor on a 1997 tacoma
No, the MAF measures the amount of air entering the engine, while the idle control valve controls the amount of air at idle.
