What is your question?
No CEL or DTC's
-Seemingly excessive condensation or white exhaust smoke
-Rough idle after cold start
(Following is seen using obd scanner and software)
-High fuel trims at idle and coast (+10 to 15 LTFT) BANK 1 slightly worst
-Under load, fuel trims improve with bank 1s improvement being more dramatic and will even get slightly negative at highway speeds. Bank 1 will almost always have the more extreme readings but at seemingly normal ranges under load. Bank 2 10 to 12 at no load, usually 3 to 8 while driving and down to 0 at highway speeds
-Mode 6 obd data shows 0 to 60 misfires in cylinder 6 after cold start. Sometimes cylinder 3 or 4 will register 1
- I have observed that after cold start and idle rough, the cylinder 1 spark advance will be a negative number. As soon as it crosses 0 back to positive, engine instantly smooths out and misfires stop. I can give it a little throttle while ignition (retard) is happening and instantly "fix" timing and smooth out idle.
