20 hrs. after my annual sevice ( tune up ) on a 2007 5.0L tks 220 hp Mercruiser I am having problems with low speed idle. Calling the mech. and explaining the problem he thinks it might be the ignition control modlel. He said he should order one incase he needs it. Is there any was to test this before ordering one? And is this even subject to engine stalling at low speed ? This engine has less than 200 hrs. on it.
I appreciate any feedback on this.
