I just got a hiace 1979 2ltr petrol camper, and i am only 19 and dont know alot about mechanics, i dont know if it is normal or not maybe for a van of this age, but when i stop and turn the engine off the van shakes and engine still runs and it shakes and moans until it has died, and to me it doesn't sound right, but i just wanna know if that is normal or if there is something i need to do, and if there is please can i have a rough price guide if i need to get it done pro cos i dont wanna get riped, thanks v much, Sam

Not normal, but not uncommon for a high mileage engine. Most of the time it's due to high carbon buildup in the cylinders. Bad fuel can cause this. The carbon will get hot and light the fuel instead of the sparkplug. Not much you can do to solve this next to taking off the heads and cleaning everything off. Also, look up "engine water torcher" in google.

It could also be too hot of a spark plugs. The wrong ones can also get too hot and do the same thing. Try using plugs with a lower heat range.

cool cheers, do u think it could be the fuel i put in then, i have been using just unleaded insted of premium
cos i mean i know it is a petrol but i wasnt told what type, cheers
