I have a 2000 Toyota Tacoma that has stalled 3 times in the past 6 months.
The engine will turn off while exiting the freeway, admittedly at a faster pace than normal, and following the off-ramp as it cloverleafs to the right. After it stalls, I am able to start it back up, but the engine wont maintain an idle. If i want to slow down AND keep my engine running, I am required to shift the automatic transmission to neutral and use the brake with my left as i keep the engine running with my right. So far I have been lucky and havent need to travel further than a stop sign in this condition, but i dont want to rely on luck to get where i am going.
This weekend I cleaned the Idle Air Control valve of all the soot that has built up over the 260k mile lifetime of the vehicle and am hoping that will fix this issue. The current malady reminds me of a previous issue where the engine would stutter when I started it up hot (fix: replacing 2/3 ignition coils).
I find it strange that I can start my car the next day and the issue is gone. It only seems to happen when slowing on an off-ramp after an extended time on the freeway with no traffic. If i start it up before it has cooled completely, it wont idle, it just dies.
If anyone has a repair suggestion or another symptom to be aware of, please let me know what to look for
