More newbie questions

I took my 72 out yesterday for a 50 mile ride. The odd thing is I could not get the heat to turn off. Even w/ the fan off I could feel warm air from the defrorst vents. I wasn't blowing very hard but it was annoying. Any thoughts?

Also, it seemed to sputter on take off, not much but I could feel it sputter and hear the exhaust pop a little. Ran well at at constant speeds between 45 - 80 MPH. Didn't push it much harder than that because I didn't want to get on the highway.

Is it tune-up time? Do I really need more than wires and plugs? I'll take brand recommendations for the plugs and wires, I doubt anyone is using the same plugs I have in my old Dodge.



Thanx

Yes it certainly sounds like your car needs a tune up which will improve it alot more then you would think. Beru seems to be a good brand for the leads generic plugs seem to work well, some people swear but the bosch platinum tho

With the heat problem is sounds like your hot water valve in the engine bay is not shutting off and due to the age of the cars some of the vents dont shut off properly which means air coming in all the time and with the hot water still flowing = hot air.

The valve seems to be fairly expensive new so all i did on mine is pushed it so that it was off and then removed and pluged the vacume lines, eventually i plan to replace it with a simple electric open close solinoid from say a garden watering system and put a switch inside.

What are generic spark plugs? Ones that just say "Spark Plug" on the box?

Make sure you get the ones in the white box with the black lettering that just say "Spark Plug" on them. For an example, see the movie "Repo Man".

Hell, see the movie anyhow, it's worth it for the general weirdness. :D

The two outside levers on your panel control the heat. At the bottom of travel, there's a microswitch that cuts off or enables heat. It's easy to push those levers in so they won't go all the way to the bottom, and that will keep the heat going, all the time. You should feel it latch into position when the levers are at the bottom and the heat is off.

It's also possible someone misadjusted those microswitches, or bypassed them, because they stopped working. To fix that, you'd have to have the control panel off.
