NO SYMPTOMS TOLD JUST A BLIND HUNT VAGUE.
what part is this, try to be more clearn
seems to me all you know now is SCAN tool shows errors not told ?
you said bank 1.
no engine told , is it a USA spec car,?
1998 is USA OBD2 based EFI.
using a scan tool is always wise after fuses all good.
Generation 7 (B) B IS 1996 UP
3800 SERIES ii ENGINE, I SEE.
THIS ENGINE HAS ONLY 1 AIR FLOW SENSOR FOR BOTH BANKS.
CALLED A MAF SENSOR.
THERE ARE fuel trim sensors for banks called oxygen sensors
front sensors, bank 1 and 2, trim fuel. based on oxygen content of exhaust fumes.
ak.a 02 sensor are no good 25 years old
the maf sensor hot wire can coke up and reads low
and causes weak fueling, on both banks, not just one ever.
we clean the fragile hot wire inside using CRC maf cleaner.
nozzel of cleaner never closer than 6inches, no damage done by the tech, gently
scan the PCM yet?
any OBD2 real scan tool works on this old dog.
