at this point u need to do a crankshaft position relearn i believe this will fix your problem. i will get u that procedure

Customer: replied 1 year ago.
But will that cause no spark on only one side of the engine
Expert:  Bandit replied 1 year ago.

yes it could cause this issue

Customer: replied 1 year ago.
How about the c0561 code
Customer: replied 1 year ago.
Why does that code only come on after the running rough part
Expert:  Bandit replied 1 year ago.

c0561 is set in the ebcm when the ecm detects a engine problem

Expert:  Bandit replied 1 year ago.

perform the crank relearn and your issue should be resolved, basicly the computer trips the ebcm code to make sure the driver takes in immediately to get repaired before converter damage occurs

Customer: replied 1 year ago.
Thank you should I also buy a new crankshaft semsor
Expert:  Bandit replied 1 year ago.

no a new crank sensor is not needed just needs to be recalibrated.
