Today, my car stalled on me 5 times when letting off the gas and slowing down for a stoplight. I had driven the car for an hour and 20 minutes with no problems. Then I got into town and the car stalled out when I had to slow for a stop light. Usually the RPM's will drop down below a thousand when letting off the gas, but this time it dropped all the way down and the car stalled out. I had to crank the motor a few times for it to fire back up. It did this 4 more times before I got to my office. I was low on gas, but not that low. I went to a gas station and put in 12.14 gallons. I have put in over 13 gallons before. Do I need to adjust my idle slightly higher? When warm, my car will drop down to about 550 rpms, so this might be too low. Just thought this was weird coming on all of a sudden. Anyone have any ideas? We will see what happens on my way home. Right now I am commuting 1.5 hrs each way to work, so the Supra has to be running tip-top!
