89 turbo supra 5 speed dies in mid shift????

[jtown125]

For those who have been following this thread and may have similar problem. I ended up putting octane booster in the gas (routine for me) and the car still stalled, but did not die. I also ended up putting premium instead of mid-grade in this time, so I'm sure the combo had a big thing to do with it helping out.

I'm going to see if this will make any difference in a longer term and post my results back at a later time.

If this doesn't help your situation, revert back to previous suggestions.

Thanks!

Be aware that the higher the octane the less power you make per unit of fuel. Higher octane fuel has mush lower kenetic energy and once you go beyond the ECU's ability to increase spark advance you lose both power and mileage.

I have no idea how that would fix your stall issue from a vented BOV... should choke up the engine just as much... You may have been experiencing an additional over-rich condition due to pinging which combined with the over-rich condition from the vented BOV.
