Erratic starting and large RPM drop
I will take your advices. Thanks. Will report on progress. The non start is the biggest problem.On advice I ran a hair dryer on the ignition modules and coils for about a minute, and the engine started, after several non start tries. Does that indicate anything? Once started it will restart with no problem.
Another comment was the in the 2005-8 years, a number of ignition modules were shipped that eventually caused non-start problems. Anyone have information on that perspective (my engine shipped in 2009), Mark
