Angry High And LOw

I have a 1986 nissan pulsar nx with a 1.6l not fuel injected and my idle somtimes goes up to 3k during starting and stays there for a few minutes or it will drop down below 500rpms and die on me what causes the fluxuation in the idle i already checked the vacumme lines and replaced the ones that leaked. oh and when it is above 3k usualy i can turn off the car then settles during restart. Other question is my right rear shock broke through the mount it was so rusty is there another fix besides cutting out rust parts and welding new metal to it?

Ummm, I'd question putting 50 cents into a car with a rotted substructure like that. It's dangerous.

No, the only fix is to cut out the bad part and weld in new parts.

As for the idle problem, likely in the carburetor . ($$$) on those.

If the vehicle is in the shape you state it's in, I'd pitch it and get something else.

Wow, I have never seen a rotted shock mount and I work on a lot of very old trucks. Sheet metal yes, shock mount…no. I agree with that your carb is most likely the problem. And yes you would have to weld in new mounts, I have seen some bolt on mounts, but they never last that long it best to do it right the first time.

Weld:

Sure, happens all the time on these. Have seen many Japanese cars of this vintage with rotted subframes and other superstructure.

I don’t work on many cars at all these days, especially Japanese cars , I mostly work on trucks or vans. I will just add this to my list of why not to buy them, that really makes me wonder about the rest of the frame. I stick with 55-80 American cars can trucks. I buy my wife new vehicles, but do not like to. I think she would be well served with a 67’ Suburban and a 454
