My 07 gt 5spd dies coasting after heavy acceleration or high speed cruising, idk what causes this, it happens randomly not all the time but when it does it happen a few times in a row

 

**** no one again

 

Have you cleaned the throttle body?? I see that so often causing unusual problems.

Plugs changed on that 07?

Any codes?

Have you unhooked the battery to reset the ECU?

 

I only have 50k, i plan on changing the plugs soon but doubt it would cause random stalling

No codes, and ya I've disconnected the battery

I'll clean the tb just to see if it helps

 

Try cleaning. Throttle body, cheap and can't hurt, try injector cleaner too. You might find a dead or dying coil plug too. I had a different issue but ended up being a bad coil. Good luck

 

I give all that a look, it just starts right back up instantly, so makes be think its something to do with the computer or electronics

 

Sounds like a job requiring a scanner, wiring diagrams, and a power probe. That's ****ty man. Hope you get it quickly resolved.

 

This is a known concern with the 3v's. The way the PCV hose is routed straight into the intake track before the TB makes the TB gum up. Starting in 2007' they put a value in the ECU for this, called "CIB slude Multiplier" CIB stands for Closed In Bore. Still, they gum up too.

I would clean your TB before you go any further. While you're doing it you can disconnect your battery and allow it to reset the PCM fully.

Thanks, Doug

 

Been doing for a while, it could go a month or 2 without doing it, maybe it's tune related, does seem to happen around when I reset my battery

 

This guy had some problems with fuel pump/fuel pressure and related sensors. Long thread but you might glean something out of it.
