Okay this has happened to me before. I get this miss fire around 6500-7100 rpm seems like a fuel cut but the air fuels are fine plus I have and Aem and the tune has been the same. Almost sounds like the two step hitting.The first time this happened to me the cam sensor was not plug in all the way. Unplugged and plug it back and it took it away. A month later after running 10.1 multiple times let the car sit and went to drive it and starting having the issue again. The cam sensor is plug made sure that both my fuel pumps are still working.

Things I have tried
Changed spark plugs
Check the fuels pumps
Made sure the cam sensor was plugged
Battery is good
Alternator good

Things planning on checking
Coils
Replace cam sensor
Check crank sensor

I wanted to see if anyone has had some type of issue like this and could guide me in some type of direction or where I should start first? Checking the crank sensor since it would be the most work. I had this issue before on My 1g and it was the computer but since this is an AEM. So swing away guys. Let me know what you guys think. lol

 

Get a data log and check the timing errors and see if you see anything strange in there.

 

Thanks guys it turn out to be the cam sensor.

 

Was the plug not in all the way or the wires, or the sensor went bad?

 

Aem or the heat fries the cam sensor on the Evo 8-9. Happens quite often to many, including buschur.

 

can a car run with a bad cam sensor.

 

Yea they will run with a bad cam sensor some times they fail completely other times they dont.
