Hello all, I have 2008 efi cultus.. it's engine was perfect. But now it's engine makes much noise, this noise problem started when few months back lahore was under water due too a lot of rain.. after that 1: it started missing cuz water was reached in its plugs(resolved now by changing seals plugs etc)...2:its idle control valve is also affected as it's RPM never stay stable when car is started in morning and RPM reaches to 3000... it's fuel pump also got weak(changing it now)...
But the main issue is of noise it's making high air like(ssssshhhhhiiiiii) sounds. NOTE: I have checked air pipes etc they are all okay.. sounds are coming from belt area.. kindly help me out in it!
