1999 Acura 3.2 TL has 87,000 miles changed spark plugs but starting RPM still low about 500; sometimes it takes two starts using gas pedal. Can you adjust Idle or does it need timing adjusted.

You need to replace your IAC (idle air control valve). The IAC, like it sounds, control the idle of your car. When they go bad they will cause the low idle and stalling. The IAC is located on the throttle body and is usually held on with a couple of screws. It is an easy relatively cheap fix that you can take care of by yourself. Let me know if you have any more questions. Thanks for rating my response and for using FixYa!
