thats good. the mechanic i went to did the job for me. he took 500 rupess from me and he sits in north karachi. he is good i think. he found out the problem for me and he did correct the problem as well.
he called me a week later which i could not go because i had to leave from paki. but im sure if i had gone he would have done it (maybe :D)
he did the tuning and he wanted me to change the fuel filters which in the second meeting.. but because of time constraints i did not but if you find someone let me know because i also have the same car as yours
