Question about 2003 Ford Escort
Without knowing a symptom, all i can say is
with a scan tool you can monitor the hz setting for the baro.
the maf produces baro info.
if the maf is bad, ussually dirty, the baro will read low
if its above 150 and your 1000 ft above sea level its probably ok.
if you have any vacuum leaks it will screw up this reading so make sure
you dont have any before using this method.
what is the symptom
