Hi all,

I'm having trouble with my VT V6 auto surging at light throttle about 30% tps opening and seems very doughy & gutless at the same throttle opening. It is fine if I floor it from a standing start. I have attached a datalog. If someone could take a look and see if anything doesn't seem right I would greatly appreciate it.

Thanks,
vc81.

Hi vc81 does it only seem to surge when lockup comes in.?
The reason I ask is the other day I had one come into the shop surging from about 60kmh up and ended up been trans low on oil(the owner was not checking with engine running) and lockup was dropping in and out quickly causing a surging effect.

Thanks for your reply vs ss. No I can only notice it from about 10kmh up to about 50kmh. It seems ok from 60kmh and up.
