Hesitation and rising temperature only on steep hill

[lunacy]

Hey all

Car is running much better now thanks to all the help off this site.

Only wee problem now is, the last two times weve come back up the Bombay hills, if you put your foot down to give it a bit more gas, she seems to stutter and hesitate. Also the temp gauge starts creeping up until we go over the top and then it goes back to normal.

No overheating or stuttering other than on this same hill, and no other wierd issues at all. But would love to figure this one out. No CEL either.

Car is 2003 BH5 tiptronic wagon.

Anyone have any ideas???

Could be normal. That's a long arse hill.

Or it could be the head gasket slowly but surely dieing a death. If you want to be sure, get a TK test done.

Yeah might be the next thing to do... its wierd as weve driven it to papamoa and back from auckland 3 times now, and had no trouble other than the bombays on the way back. Seems that hill must stress the engine a bit.
