Looks like we all are bitten from freaking untrained shit mechanics, i am having same problems the car jerks alot specially between 2-3k rpm keeps missing ,lagging and if you floor the car it will give you a hard jerk and then move forward. plus all the vaccum pipes are messed up that too by the ushtaadd gggg's i am totally fedup now. I need a expert mechanic who actually know's about cultus carburetor in Rawalpindi please help.
