Ok here a quick run down. I have a 2005 G 6MT, and I have Oil Consumption. I wanted to built my block for FI, so I never worry about the consumption of oil, as I always changed my oil every 3K with AMSoil. Being that kids cost alot of money, my engine built is not going to happen anytime soon. So I deciced its time to car to the dealership to get a new motor. I spent last weekend removing all my Mod's (Painted Valve Covers, MREV2, 5/16" Spacer, K&N filter, Z-Tube, HFC's and UR Underdrive Pulleys set). After fighting with my valve covers gaskets to stay on, my friend who is a Nissan Tech disconnected my main engine hardnesses from almost everything and peeled it back so the valve covers could go on without the gaskets falling out. After all my stock parts were installed, I started the car and it sounded like a WRX/Sti. I was throw a DTC P0300 (engine misfire), and on my drive home I got P304 (misfire Cylinder 4). Over this past week I to everything I could think of to toubleshoot my problem. I replace the spark plugs, the swapped coil packs around, and I still got P0304. I did a engine compresstion test, all cylinders are well with limits. I didn't test the injectors, or do the injector clip node test because that's too much of a PITA, and I never touched them, so that should be covered under warranty if I have a problem.

Which bring me to my question, when I drop to the dealership, should act dumb or should I seem like I know what is going on. (I know not to tell about my toubleshooting) I'm asking because my dealership is a bit snobbish, and they feel OEM is best, if could have been made better Inifiniti would have put it there. I also can't go to other dealership because they are like 2 hours away.

Thanks for any advice.

 

Reset your ECU. The car might be running poorly because the ECU has learned how to modulate fuel/air/timing characteristics based on the car with the mods installed. Now that you have the mods removed, it needs to start from ground zero.

 

Thanks but that was the first think I did.

Just play stupid bro. They have to give you a new engine anyway, so they probably won't even waste the time to fix it.

 

Sounds like a plan.

 

+1, just mention the problems you are having and let them do the diagnosis.
