just need to discuss an issue with my car civic 05 manual exi.
i got my timing belt opened twice for a sound that looks like of timing bearing but every time the bearing came out working fine. the mechanic just its a belt so he opened it up and did some thing with bearing and said it will be ok now but the sound is still there its just like "GHOOOOOON". its not power pump for sure.
second issue is on old start engine makes noise and gar gar gar(foundatio non front is broken) and also throttle pedal is very hard for the first 10 minutes and car is slow then once pedal gets soft car moves a lot better.
one issue is with RPM of the car 9/10 times the RPM dropes when foot is taken off the accelaration pedal and then comes back to normal causing engineto vibrate even on reversing the car for 10 m the RPM drops. also on turning the steerin wheels this happens.
what can be the reason for RPM drop every time?
