What kind octane fuel are you using?? Supreme is recommended for the ka24de. I believe the fuel you're using is not the problem. It should be something else. Check fuel pump, regulator, rails, etc. Good luck.

could be one of the (too) many devices that controls the idle has gone bad. I'm pretty sure all of mine are on the fritz.
