[QUOTE="Evan5469, post: 11095251, member: 14423"] I'd start with the small stuff first. These codes both indicate lean coniditons on bank 1 and 2. So start by cleaning the MAF. It's a good maintenance thing to do anyway, but it may also help resolve your problem. Also, double check to make sure you don't have any vacuum leaks. You stated you've deleted the PCV and EGR so while messing with all those hoses, one could've been overlooked and left disconnected. Just a thought. Also, were these changes made in the tune also? If not, your Cobra will not like that they were deleted with no changes made in the computer which could bring up the issues you're having. If those don't fix the issue, try datalogging to see what your fuel pumps and injectors are doing. The problem may be there and datalogging will make it apparent and easier to track down. [/QUOTE]
