Hard to start

[CrazySupra]

I searched but could not get the answer. Both of my Supras when I drive them for maybe 30 min or better and turn them off wait about 15 min and they will not stay running without revving it up. Kinda embarressing. Just need to know what needs fixed, changed, or cleaned.
Thanks

CSI switch? Or maybe fuel pressure up vsv?

Kinda odd that both my cars do it. Where is the Cold start injector on GTE?? DO I clean it o replace it?? What about VSV?? What to do??

My car does it as well & sometimes holding it at WOT isn't enough & it dies. Only code is 52 & a screw on one of the things (can't remember the name, i keep forgetting, the regulator & the other thing) on the Fuel rail isn't there. IDK about fuel stuff..

Check codes.

Csi is only used for starting. After the engine has started it is not used.

Explain more.

After driving a bit hard, i try to start the car after lets say 30 mins. it starts & dies immediately, hold the gas down & its like the timing is off & i guess its the Knock sensor that retards the timing?? Its getting worser though.

That's what both my cars are doing? Atleast I know i'm not crazy....

The csi time switch could be at fault but the injector itself is not.

Rest pressure...

This might sound stupid but how do I do that??
