Ignition Coil Thread (UNDER CONSTRUCTION)

[riced_roach]

You have primary and then secondary. Remember the coil is a transformer which is basically a step up transformer. There are more windings in the secondary cct. The aftermarket coil should meet the same resistance in the factory specifications. primary resistance is checked by putting a ohms meter between the +ve and -ve of the terminals.

Well the thing is depending on what kind of system the older ones had an internal ballast resistor or some had external ones. I would assume a non ballast resistor type coil has aprox 1 ohms or so and the ones with an internal ballast has 2-4 ohms. I think the claim of having too a high primary resistance will create a miss is bullsh!!

resistance may effect how the primary voltage energizes the primary coil. The MSD systems use the HVC coils in the digital 6 units to engergize the primary faster with low primary resistance. Too much to discuss but basically get a coil with close to factory specs.

coil faults normally occur once they have heated up,which would cause a miss or no-start fault

What coil did you get? Did you mount it properly? Some coils need to be held a certain way.

My coil says to use a ballast resistor but we don't need one.
Make sure the spark isn't arching to one of the terminals. I had to use electrical tape and a thicker wire boot.

i had gotten a cheapy accel coil, i am going to get a blaster 2 next week.

[A20A1]

Blaster 2 and the Accel super stock are very simmilar, I have both and never notticed a difference between the two. I also have a large accel super coil and that one out performs both... I've also heard good things about the MSD Blaster SS.

[FoX]

do you have a part number for the super coil that out performs? i think i want to try that one.

[Blkblurr]

I aggree with Riced Roach. Primary resistance has nothing to do with missing. Shorting due to low resistance (ie a water problem or poor insulation) can cause this. The high voltage produced by the secondary will arc over when the insulation is bad or water causes lower resistance internally. When arcing occurs, no spark gets to your plugs.

ups dropped off my accel coil yesterday. I rigged it up with my friend. couple questions I have is,
did you guys have any problems reaching the positive and negitive wire to the coil?
and what advantages did you guys get out of it??

[od2681]

i had some trouble but it worked out fine...
I for one felt that the car would rev a little quicker now...heard some pss noise from exhaust for some reason..hahah...
and gas mileage is a little better

[atom1414]

the positive and negitive connecters are exposed. do they need to be coverd with something, or will they be okay??

pss noise??

What other things do I have to do to my car when i put on my new coil?

[k-roy]

Not really much. Maybe increase the gap on your spark plugs. I replaced mine and gapped them to .050 inches and advanced the timing a few degrees.

[customandsound]

why can't i get in to the how to on this ?

what do you mean by get into?

I have increased my ponies by placing a little K&N Filter sticker on the little back driver's side window.

A few days ago I went out and bought the Accel Super Stock Coil. Took me maybe 20 min to put in, and works fine. I noticed the idling seemed to be better, the car seemed to respond a bit quicker (accelerating), and the top end felt better as well. Not as much of a difference from getting the NGK V-power plugs and 8mm wires, but it helped. Also I have my plugs gapped to just over 0.050. Also, I had my plugs gapped before I had the coil, the car seemed to perform better. I am not sure if the coil has helped THAT much, but the old one was just that, old, so at very least it can be written off as maintenance. I paid about 47 bucks CND from PartSource. They said the MSD was more expensive, but as I read on here the Accel was better? Anyways, good luck.

im also having idleing problems with my 89, i just ordered a header for it friday, and i already have the hi flow cat and cat back, this week im getting a new coil

[SharkyX]

i put the coil on and now my idle drops a bit at stop, also if im in reverse and turning or anything it stalls, it seems like my idle is waaayyy too low compared to what it was, any ideas guys. Also i drive an Automatic. Fuel Injected

[shepherd79]

get 5 speed, LOL.
but on serious note. get carb cleaner and spray the insides of TB and intake manifold.
it helped me. after 20 minutes of cleaning my idle jumped by 300 rpm. it fells a hole lot better when accelerate.

[SharkyX]

if all that was dirty wouldnt it have done that with my stock coil on? what is it about the blaster coil that could trigger something like that? also, just to be sure, the screw that i turn to rais idle , i take that completly out and spray that and the inside through that hole? Alos do i do the cleaning with the car off or on.

[accordlxi2.0]

you got a blaster 2 coil??
i just got one in i'm sorry for interupting . . . . . . . . . . .but how would you go about putting one in???

[od2681]

adjust ur idol
it shouldnt do that though
after i installed my accel super stock...it idols at 600 or below sometimes on hot days..haha...and never stalls

i followed the turorial for the acell coil thats in the "How To" section of the forum. Same install

[SharkyX]

yea noticed car idols way higher in Park then in drive, never paid attention before. but i sdjusted it up and it seems ok now. Just didnt realize it would do that lol. Wish i could find out what the exact reason is.

[shepherd79]

i am telling you, your TB is dirty.
remove the air intake hose, ad spray the carb cleaner in there.
let is soak. you will see some dirty brown may be black stuff running out. start the car, it may take a while since carb cleaner doesn't ignite very good.
after you have your motor running. just keep spraying and reving the motor.
shut the car off. open the throttle body (engine off) and spray everywhere. go get dinner or smoke break or whatever.
come back. start the car and spray again with the engine on.
let it idle after that for about 10 minutes.
after this kind of cleaning you will see your idle will jump higher.
the carb cleanner $1.99-2.99. 30-40 minutes of your time, better idling car= priceless.
