I have a 94 SC400 that was stalling when I let off of the gas. I changed the MAF sensor and it worked fine except when I gave it gas to pass another car it would miss a little. Today the idle stayed high and then after about 20 minutes it started stalling again when I let off of the gas. It cranks fine but won't stay running unless I give it gas as soon as I crank it. It runs as longs as I keep my foot on the gas. Not sure what do do from here.

Have the throttle body and IAC cleaned and retest. Seems the idling speed is erratic.

Is the Check Engine Light indicating and have you truied to retrieve for trouble codes?

Check for vacuum leaks between the MAF and throttle body.
