hi all, on my 1999 yaris gs when the engine is warm the revs will drop on idle. also when stood in traffic lights etc, sometimes when pressing the accelerator nothing happens. i have to pump it a couple of times for it to work. would be every greatfully if any one could point the problem out for me.

thanks

I have the same problem with my 2000 GS.It's had a service and for my peace of mind I fitted new plugs but the problem is still there.I did adjust the tick over with the adjuster on the throttle cable cam which did help a little but the "flat spot" is still there.I have also cleaned the MAF sensor.
