Nfx Engine - 106 Problem

[omri617 18]

Hi

I'm trying to help a friend with a problem with NFX engine.

His car runs fine till the engine temp gets to 69 .from 69 to 90 , the engine chokes .

Map sensor changed - no change.

Temp sensor changed - no change

ECU changed - no change

 

What can it be??

Thanks

lambda sensor is likely as it is not used until it has warmed up.
