Has anyone come across from memory around 2006 Vectra C22SE cutting out when the temp gets to around 93degree's.

I didn't make note of the exact fault code as I thought it was weird but referenced ECU rom error & I think it had something to do with earth maybe?

I'm 99% sure it will be the actual engine controller failing but be good if it's a known issue with them.

sorry it's a Z22SE & build date is 4/05 & Aust compliance date is 2/06 & is a ZC Vectra

The service number for the ecu is 12581937

I had one of those cutting out and it turned out to be the IAC gunked up. When you see where it's mounted it's destined for problems.
