thanks,

no the 16vlv doesnt have the adjustable valve timming.

I retested the secondary ignition and surprise: the burn voltage is now at 1.2kv (normal)! I dont know why.... So now the trace seems to be ok...

The possiblity of a hole is high, in fact I'm pretty sure I have one between the O2 and the engine.

So here's what I will do:
-Fix the hole;
-Buy a new EHA, it could explain the lamda jump down at higher Rpm.

I'll give you some new as soon as I finish thoes 2 things,

Thanks alot!!!
