did u succeed ?
I mean are you facing check engine light problem or its gone?
My one used to come a lot, my cng mechanic said, your air filter is very dirty, this light might be appearing becoz of this, so i purchased air filter for 220rs and the check engine light was gone for almost 2 days!
But, yesterday it appeared again!
one thing i will say that my check engine light does not come all the time (before air filter removal or after)
It just comes for sometimes and then goes off!
Sometimes, i drive almost 90kms with no check engine light on on dashboard!
what i think is that some connection is loose or the wire is touching the car body (just thinkings..)
