Car in question, 2004 Chevy Malibu. Purchased 3 years ago.
Mystery 1.May of this year started having fits of not starting well. Sounds like it should start. Problem is intermittent. So far has always started on the 5-7 try.
Haven’t noticed that weather or temp. has any effect.
Mystery 2.When stopped and running there is a noticeable " irregular heartbeat".
Local dealership can’t seem to solve. Counting on you gentlefolk. Thanks.
