Tach needle jumping again

Hows it goin ppl? A little over a year ago, i had a problem with my tach needle going crazy and revvin on its own. I posted the problem, heard it may be the ignition coil, and had it replaced. Things went back to normal. Today, i drove to school (night class), parked my car in the garage, put it in park, and all of a sudden.......the tach needle starts goin crazy. not as crazy as it once used to go, but crazy enough to notice. I replaced the ignition coil a little over a year ago, and its happening again?? Is that normal? I put in a stock ignition coil. Should i replace it with a MSD blaster coil? Its irritating because i'm gettin alot of work done to my car as of late, and this just adds to the ever-growin pile of things that need to be taken care of. Any Suggestions? Comments?

msd / accel / mallory / summit etc ...
they all make aftermarket coils that perform far better then a jobber replacement or oem coil

they are worth the investment and speak to roooooosplash about a bracket - or make u're own like i did

use an impack driver
or spray down the bolts with lub and leave it for 30 mins then come back to then
stuck bolts will happen to 10+ year old cars

Ok well i just started having this problem the past week now. And at times my tach just sits at 0 RPM and does not even move. And it seems as soon as i get on the hwy its fine but after about 10-15 miles at the same speed about then it goes nuts. Im willing to try the ignition coil.

But really why is it that when the ignition coil goes bad that the tach jumps? How is the ignition coil even connected to the tachs movement? Does anyone have a good explination. Im beginning to think it might be a connection or my tach is going bad.

the ignition coil is connected to the tach cause thats how its reads the engine rpms. so when the coil's resistor goes bad its not reading the ignition signal anymore and thats why the needle starts jumping. i have a stock coil i bought brand new last year but i just pulled it out since i wanted the msd coil, it works fine and if you really dont want to go the aftermarket route im willing to part with it. keep us informed.

OK so I went the route of getting a brand new coil 2 days ago for $132 with tax. But im hoping i will get that all back when i sell my car.

It took me about an hour to take it out and put the new one in. The top left bold was easy to get to with an extension and 10mm socket. The top right one was a ***** to get to. Took forever to loosen that thing. But best was was a small 10mm wrench. The front left was the same. Also something to watch is when you get it all off there are lil spacers that you dont want to loose. I droped one and it took me 10 min to find the damn thing.

Im installing new spark plugs and wires tomorrow morning when my car is not hot from driving in around. Thanks for all the help and hopefully things go well.

PS I really notice a difference with how smooth my car runs now. Much better then it was before

132 ?? damn bro that is expensive
did you get some booty with dat too ?
I'm guessing that u bought it from a Honda dealer and that it's an OEM coil
if you wanted to keep her stock, good decision, however just an FYI, @ summit racing, a msd blaster coil is like 25$ and the bracket another 3-4 $ and it will give u a much better spark

yeah i know but msd is not stock and i will get the money back when i sell it most likely so im not to worried. I put in Bosch platinum 2 spark plugs this morning.

I contemplated for a long time about going that way but figured if i was someone buying the car i would be a little worried at what else they did with it if there was an aftermarket coil installed. But then i also see that it will produce a better spark then OEM but oh well its done with........
