I need help, I have had a misfire on bank one for over six months.. the codes that are generated are 300, 301,302,303, 341, 1340. I have done the following (not necessarily in this order) replaced the O2 sensors, all the spark plugs, the #1 variocam solenoid, had the ECU tested, had the engine compression tested replaced the camshaft position sensor on the # 1 bank. I've check the wiring going to the variocam and the camshaft position sensor, along with the wiring in the rear trunk. I even sent it to an Indy garage and he looked at it for 4 months and gave up.

Sorry so long, here my question(s); the car will run fine until it warms up to about 120-140 degrees then the CEL will start flashing then go solid.

What happens at that temperature? does the cam begin to shift?
