hello, all. thanks for all helpfull answers and suggestions. here is new three problems.
- the car has 102K miles and i have no record of when was the last time of changing timing belt
- a friend told me that rear shock-absorbers are without air and must be replaced.
- light "service engine" is on and the OBD-II code is PO401 (insuff. EGR flow detected)
I have three questions to each of the problem:
- As to timing belt i am just scared by all forums where it causes engine die. Maybe if engine works just fine timing belt should not be touched at all. Will i feel somehow if my belt is relatively new or not?
- As to shock-absorbers is it really unsafe to drive now (or in coming winter)
- As to EGR what is most probable cause of this problem. (the previous owner gave me the car with very dirty oil; could that affect EGR seriously?)
