1G Check engine light

[Elpizer2]

Hi guys

There is something weird happening in my car

When I am WOT under boost check engine light comes. No DTC on ECMLink nothing. When driving normal check engine light is off. It happens only under boost.

Also it blowed the 100 amp fuse.

What do you think could be?

Can you see your knock sensor? If it is old, they tend to ooz out the semi-solid center. Just making sure it is ok is all.

Knock sensor looks like new, my head gasket is gone, I'm replacing it right now, I think this was the problem, I'm installing Cometic gasket.
