sorry brother apko time se reply ni kar saka...
Brother throttle body mn total teen hi chezain hai important...
Butterfly valve...
Autochoke jisay actually Idle Air Control valve kehtay hain...
aur Throttle Position sensor...
Problem ya IAC mn hai ya TP sensor mn...
Aur ye problem computer scan mn nahi ata... TP sensor jab full dead ho tab deta hai check engine otherwise nahi deta...
Throttle body change karwa IAC aur TP sensor change ho jatay hain to chance hota hai k problem theek ho jay ga.... lekin kabli ki guarantee koi ni hoti...
Aap TP sensor ko khud check karain.... aur autochoke mechanic ko kahain k chnage kar k dekhay... lekin is shart pe k agar masla theek na hua to wapis ho jay gi...
If u are interested I will tell you details about how to check TP sensor....
