My cousin and I went and looked at an 07(24v) ST 6 speed ran great, super clean 50,000miles dude only wanted $22 for it. When I shut it off, the motor seemed to shake for about 10 seconds after the key was off. He said thats the way the comp. on the truck was set up to do. When I did the DTC it flashed the check engine light 10 times and gave a #10 then flashed 10 more times. I started it up again, and it did the same thing. Ran for about 10-15 seconds after the key was shut off. Sucks cause it was a desent deal on the truck, I thought. What's up?

Thanks

Possible the injectors are shot. Check the oil and make sure it's not thinning out with diesel.
