ok i know this sounds stupid but... everytime i start my car after its been sitting a while it makes a wierd almost grinding noise for about 2 seconds...just on start up ...anyone else have this problem...and what do i do to fix it if anyone has any suggestions

 

Timing chain? Low oil pressure on start up?

Just guesses.

 

will this damage anything

 

how many miles?

if u have 25K and above.......change the fuel filter

 

about 90,000 but its been doin this since 30,000 i was wondering if any others had this problem?
