My 2006 Saturn Ion 3 sometimes has trouble cranking. Once cranked, it usually idles low (around 500rpms). The car will proceed to die when I shift from park to drive. What problems come to mind? (On a side note, this only occurs during hot weather. The problem seems to disappear during cold winter months. Odd fact, but maybe helpful with diagnosis.)
I'll give it a try. Thanks!
