Sounds like an ignition problem.

yeah I'm gonna borrow my mates timing light tomorrow and double check but my mechanic already did it for me so it should be right

thats what i though but if it runs fine when babying it and it only occurs when tvis is supposed to kick in so I'm not sure

Sounds like it breaks down under load, dizzy cap, rotor button, leads, plugs. Something like that. Check the timing, then look at the leads etc.

If you disconnect the tvis and keep it open, that should tell you if it's tvis. It doesn't really sound like it is though.

Sounds like ignition related or possibly map sensor issue.

Check ecu for codes?

how do u check ecu for codes

[hilux05]

i had a similar problem with mine. turned out to be the complete distributer being stuffed.. something inside it was cracked and was sending out two signals to the ecu and made it die after i reved it.

so yeah maybe borrow someones that you know works properly..
