My engine moves when i turn off the car...HELP!

[detser122]

Ok, this is what happened, i was on my lunch break on the way to get cash for some grub, when i turned off the car and took the key completely off, the car started to move like if the engine was jumping. I heard some pushing noises like if the engine was trying to start again by itself. I tried it a couple of times and it did the same thing. Untill i drove back (without eating) and let the engine run a little bit and turned it off after like 2 minutes and it turned off like normal...what the hell is up with my car? Is it witchcraft? Help me guys.

it was probably dieseling

yeah dude, my old dodge shadow (RIP) did that. It had a vaccuum leak in it and it rev'd kinda high, and when I turned it off the car would jump and kinda spudder untill I took the clutch off, I replaced the EGR valve and that helped

hah, my friends chevy c-10 dieseled all the time. came home for lunch during school one day, it diesled for about 20 seconds.

I don't know how in the world a computer controlled car can diesel.

use better gas. my old trans am used to do that when i put 87 in her. i forgot what it's called but if you just use 89 or 93 oct it should go away.

try running an engine cleaner through it. you might have some carbon deposits that are getting hot and igniting remaining fuel. how more gas is getting in there, i don't know. maybe a leaky/dirty injector.

seafoam the entire thing, head, block, and fuel system.

my trans am was carburated. I don't see how it would sputer when i put better gas in cause it wouldn't have spark but it did work.
