Hi all, please help:
Have just went to tune my 4g92 sohc in a foreman`s shop that has a
machine called vendi to read n diagnose my ecu....
upon connection, the throttle positioning sensor is fine but when
checking the logged faulty check code by the ecu, i was totally shocked
to find that my car has bunch n bunch of error codes!!!!
codes such as ISC SERVO ERROR, AIR FLOW SENSOR, SPEEDO, BAROMETRIC PRESSURE SENSOR and some others
which i`ve forgotten are on display in the code reader.......
though i tried disassemble the air flow sensor wiring (adaptor), tried
starting my car n tested driving with the check engine light on (my wira
is the 1st batch open loop, thus i think it bypasses the air flow sensor
n follows
default manufacturer`s ignition timing), the power sux big time, it`s
like driving a 1.3....
then reassemble that air flow sensor adaptor back, ok no more check
engine light,
everything is as smooth as silk, power is back......but i was really
wondering, why did i have all sorts of faulty codes when my engine is
running smooth n powerful???
could anybody help???
