Question for you guys, When i shut my car off the car will diesel for about 5-10 seconds when I run Sunoco Ultra 94 gas unless i turn the car off in drive. If I run Mobil Premium 93 I dont have that problem. Is it because the Sunoco has a little alcohol in it, I've heard that. What are your guys ideas on that. Any help would be greatly appreciated.

Thanks,

try cleaning your spark plugs. ive heard that the carbon will build up and glow red hot and that will actually ignite the mixture. but im not sure why it would do that on ultra premium and not a lesser fuel? should be the other way around.

i know how you feel though, ive got a 64 jaguar E-type. damn thing starts great but will NEVER shut off. i have to put it in gear and step on the brake just to get it to stop clattering after i pull out the key.

gotta love that british technology
