I have a 2001 RX300 (85,000 miles) that has started in the past few month OCCASIONALLY experiencing an idle speed problem at start. When the incidient occurs, the vehicle has difficulty starting unless gas is applied...then when I back off, idle speed drops and vehicle stalls.
So far, if I apply power (gas) while applying the brake, keeping engine speed up...until I can enter a road/highway...after a few minutes of running, the car is fine, as in it maintains proper idle speed the next time i come to a stop.
This problem is intermittent...probably only occurs once in every 10 starts or so at most.
There are no other symptoms (no check engine light or anything like that)
Gas mileage appears to be largely unchanged, and accelleration is basically normal.
It does not seem to be tied to any gas level in my tank at the time
Any ideas what this might be? (No, I have not take vehicle to a dealer yet) I'm going to put in some fuel injector cleaner into the gas tank tomorrow...but just curious if anyone as any experience with this. Clogged fuel filter?
Thanks for any help.
Randy
