Whats up guys, I have this problem with my camaro that it has a misfire on the 6 cylinder and sometimes on 4th cylinder. I've been taking a look at it checking everything that could be causing it but all those thing are working just fine. When I turn it on its all good until Im driving it just starts to loose power/ hesitates.

 

Change the plugs

 

How if I just changed them

 

You didn't mention that before.
Check the fuel filter.

 

the fuel filter was changed... also I cleaned the MAF sensor checked the compression, fuel pressure cleaned injectors, checked the coil packs, new spark plug wires, checked for a loose ground cable also I took it to the electrician and he only found the misfire and no cause...

 

Plugs wires fuel filter etc. Move the coils around to see if the problem follows the coils. You can do the same with the injectors. Test your fuel pressure

 

I did all that but one of my friends also a mechanic thinks it can be the ecm... Do y'al think it can be that?? Even if the electrician didnt find that wrong??
