Dear Nido and all...
once again I would suggest and recommend and say what I had already been saying.
Please STOP RELYING on dealerships....dealerships are a shitt...I have been running a workshop for three years in Islamabad and during that time, I came across a lot of times with these dealerships regarding their labor, spares and stuff. 99% dealerships in Pakistan are provide non genuine parts at extremely high rates to market with their dealership stamps over it and doing business. Their labor is not at all skilled and the sad part is our poor innocent people think dealership is an ultimate and authentic solution to their car. PLEASE STOP RELYING ON DEALERSHIPS, they have poor quality and high costs.
Prefer the local well reputed mechanics and vendors for parts/accessories/repairs.
Regarding your prob, dear bro first of all I'd like to welcome you to PW..enjoy your stay here Secondly this is just a small tuning problem and nothing else. Go to a well reputed mechanic preferrably a CNG technician, give him a demo of your prob and he will have it done for max 200-300 rs. its not more than that.
Best of Luck
Regards,
