Hello, I have a problem with an m54b22, I took the intake down in order to replace the vacuum hoses, said and done, working there I noticed that the camshaft sensor on the intake was melted on the block, the car was going well ... I mounted the intake, and I changed the camshaft sensor with a new one ERA AFTERMARKET ... I started the car everything perfectly, I turn and my car goes in 5 pistons ... I thought it was the problem from the coils, I reversed them but he still misses me on cylinder 5 .. He was walking normally until he was cutting the spark at cylinder 5 ... Now he only goes in 5 pistons, the 5 is dead, he doesn't have any electricity at all ... Opinions please! Thank you

The head, not the block. But please post a pic of the melted sensor as I don't understand how can this happen.

and I changed the camshaft sensor with a new one ERA AFTERMARKET ...

This is a bad idea. Leave the melted senor alone as it was working fine.

He was walking normally until he was cutting the spark at cylinder 5 ... Now he only goes in 5 pistons

Double check the injector connectors having good connection.

Capul, nu blocul. Dar vă rog să postați o poză cu senzorul topit pentru că nu înțeleg cum se poate întâmpla asta.

Aceasta este o idee proastă. Lăsați senorul topit în pace, funcționează bine.

Verificați de două ori conectorii injectoarelor care au o conexiune bună.

Yesterday I started the car, it worked perfectly in idle, after I accelerated it At 6000rpm it started to run in 5! The injector on the 5 is not opened by the DME

That's standard failsafe on these cars. If the DME detects a catalyst damaging misfire it shuts down the injector to that cylinder. On the next key cycle it starts all over again.

Picture of melted sensor please.

Is the earth for the coils connected on the head between the coils?
