Engine that Diesels after shut off
I am a new proud owner of a beautiful 1970 240z and I have noticed a couple things about the car that seem like easy fixes, but I would like to hear a little from the you all.
First thing that really stands out is when I shut off my car, the engine continues to try to run. Do these cars have an electronic shut off valve in the carb to prevent this from happening. I think the problem will be remedied a bit after I do a fuel treatment along with a nice fresh tank of gas. What Octane do you guys suggest for the original Inline 6. I haven't noticed any engine ping under acceleration.
Second, the car seems to run a little hot, though I am not really sure if i trust the temp guage yet. When I am in stop and go, the temp goes just passed 3/4 on the guage. It seems to do it pretty quickly like maybe 5 minutes of slow driving. It immediately goes back to half way once I am under way for more than 30 seconds. Probably will get its oil changed soon, any suggestions for weight and brand.
Lastly, The **** hood latch keeps popping up. Know of any sources to obtain a new mechanism.
Once I can get my hands on a camera I will surely post some pics of the car
