Dear Pakwheelers !
I was facing bad caverage, loss of power and decreased pick in my vitz 2005 from quite some time.
In the first instance i got the engine oil changed as well as oil filter and replaced air filter
with genuine Denso one but felt no improvement.
Yesterday I made the throttle body washed with cleaning fluid and changed the plugs with original
Denso iridium tipped. I also got its Cat Converter removed and O2 sencer cleaned. After that I
noticed the following changes :
a) The pick has somewhat improved.
b) There is an increase in engine sound .Increase in RPM is also quite noticeable.
c) The acceleration pedal feel a bit soft.
d) Improvement in average has not yet been calculated.
To solve the problem of elevated RPM my mechanic has advised me to reset its ECU by unplugging
battery's -ve terminal for 1 or 2 minute before plugging it againn.
I request your advice regarding :
Is this the correct way to reset ECU.
Will the reset have any negative effects on engine performance?
How else can i further increase the pick and average?
DEAD EDIT: Moved to correct section
