You're going to scratch your head at this! For fuel here we have 87, 89, and 93 octane gas. I usually put in mid-grade 89 octane fuel since that is what I believe the manual recommends. Yesterday I decided to put premium 93 octane instead, and the check engine light and starting issue went away!
I have not done anything, the plugs and wires are still sitting I have not installed them. It's only been a day but both issues seem to have gone away.
I will look into it, its obvious that the true issue is with the fuel injectors. I became side tracked with the idler pulleys, tensioner, and serpentine belt. My lower idler pulley was nonexistent, all that was left is the metal rings...
My 14' durango has been experiencing the same starting problem for a year but without the gas smell. Over the past year it has gotten progressively worse. It only has the issue when sitting for between 1-6 hrs. Cranking first thing in the morning is no issue nor is it an issue turning vehicle off then immediately back on. Dealer just replaced the TIPM to no avail. I'll request the injectors be inspected and see how that works out.
Any luck on a resolution?
