idle problem
when my car is idleling and sometimes while is warming upsometimes the idle goes a little higher after a few minutes.
i have clean the filter,maf,tb and i have changed my pcv valve.
could it be my coolant that needs to be flush or what other things can i check?
First check for any codes with a scanner, whether you have an SES light or not.
A vacuum leak usually cuases the idles to be higher than normal. Also, a failing IAC (Idle air control) valve. Its on the TB and has an electrical plug. top left side of the tb.
