Runs Rough - Cold Start - Open loop 6.0ls2 E38
I am at a loss and was hoping I could reach out for ideas, currently when I cold start it takes multiple starts to get the engine warm enough to run as its running unburnt fuel odor is strong. It will run very rough with a low idle and sounds like its misfiring or running on only a few cylinders. See "1_Cold Start - Run to Stall"
If I disconnect the MAF harness it runs much better.
After several tries and the engine is warmed up a but its starts run better, but is still very questionable, any attempt at adding power will not result in the desired revs. "2_Cold Start - Run to Closed Loop"
once it is in closed loop and I restart then the engine runs much smoother.
Any thoughts? Ideas? Thank you in advance!Attachment 144290Attachment 144291Attachment 144292
