hey guys after a power run on the dyno if you get off the gas the engine light comes on and the car stalls.

but only over 4000rpm and 10psi

if you step off it and as it starts to stall you jump back on the gas the car will be fine its only if the throttle body

snaps shut and stays shut.

I was thinking maybe idle control sensor

but that's not an educated diagnosis.. my tuner is trying to sort it out

any ideas

I need to get on the road it eating me alive :thumbsup:

thanks james

just received further info... it only does it when selecting the gears.. not in drive. not in neutral.. must have something to do with the tune of the box.........maybe :bowdown:

Could be way off base but you could try resetting the TPS?

Nothin' to lose.

ill let them know

but it runs fine in drive its only when manually selecting the gears (4speed auto)

cheers james
