Car is running .. idles very low but it starts and runs i'm throw code for TDC (top dead center) #8 what should I do? to resolve this issue?

 

from what i've found in search it suggests a new dizzy.. true or false? Can I just drive it like this it runs fine?

 

pull your positive battery post off . . tap your breaks wait 15 minutes and see if it goes away . . if it doesnt then you know something is wrong .

 

i've been driving it a little it seems to bog a little low in the rmps i dont know if the ignition timing is off a bit or what

 

Partly true. The TDC sensor is one of the three engine control sensors built into the dizzy housing. An OEM dizzy housing by itself is cheaper than a whole OEM dizzy. Lots go aftermarket though. Aftermarket dizzies are not as reliable but often do the trick for some time.

It is possible that there is just a wire that is loose. Go to the shop manual at http://ww1.honda.co.uk/car/owner/workshop.html and see the tests for the sensor there.

I expect your gas mileage will improve with a new dizzy housing. IMO those three sensors do degrade with time. I recommend replacing the housing every 150k miles/10 years.
