Need help on my 2000 accord 4cyl. Car cuts out when I come to a quick stop or idle runs really low after I rev engine up. Would a weak fuel pump or clog filter cause this? Any suggestions?

Thanks

 

You don't have a normal fuel filter. Check for problems with pump by measuring fuel pressure.

Idle problems can be caused by a few things...
Find & fix any vacuum leaks.
Make sure there's no air pockets in the cooling system.
Clean throttlebody.
Clean IAC valve.
Set your base idle.

 

Thanks for reply, Car runs great once you get going, If you come to a stop or sitting and hit the gas pedal and let go, Idle drops do to about 3 rpm and sometime dies out. Would it be a problem to adjust the idle screw on the throttle body? also is there a way to test the map sensor?

 

The idle screw on the throttle body is for the base idle. It doesn't work well to set the operating idle with that because the IACV will be trying to work against you.

 

Thanks for info. I did bring the idle up a little and seems to work.
