- 1971 Coupe. 302 2V - C4 trans
All,
We (myself and my son) recently bought a nice driver 71 coupe. 302/2V, C4, pwr brakes/steering. The machine is in good condition, we drive a little bit most days, never too much or to far.
We have seen on many occasions that after turning off the key, the engine will "diesel" a bit (what I learned to be "continuing to run after the switch is off"). No big deal, but probably shouldn't be happening.
I'm in search of the potential causes, hints of "this might be happening" or other reasons this should be traced down and dealt with.
So any help with this? Concern? or annoyance that just doesn't matter?
One other item I have found is that recently I had a heater hose blowout. The water spray from that killed my engine during the event, and after replacing the heater hose, I found some spark jumping (improperly) from the coil wire (just on top of the engine next to carb) to ground on the heater hose clamp (causing some significant stuttering of the engine when it occurred - not often..). I've readjusted the clamp to distance it from the coil wire, but too soon to tell if that has solved the issue or not. I only mention it in case this spark jumping could be related to engine off "dieseling".
Whats your take? What can I do to isolate, and how big of a deal?
