Will MSD Blaster Coils Smooth a Out rough Idle? I have a large cam, and I was wondering if MSD Blaster coils would help improve my idle a bit, because they have multispark?

blaster coils The coils built by MSD are no different from the factory coils in the regard that they will only spark or fire as often as they are triggered by the controlling ECU. They may have a higher voltage output than the factory coils, but if the factory computer is controlling them, they will not operate in a different fashion than the stock coils they are replacing. My own two cents worth would be to look at the rough idle as a symptom and explore fuel mixture and timing settings to try to improve the idle quality with your current setup. My vote would be to save your hard earned money.

msd coils will spark with more voltage so the unburnt gas that use to go through your engine with the stock coils will now be burnt which in return you make more power bc all the fuel is being used and not wasted. but the coils will not help the idle at all, my thoughts are to buy another cam with with high duration low lift and like a 115 lsa...

If you don't like that sound something is seriously wrong with you.

To smooth out the idle of your current cam, you have to increase the idle speed and add timing....still not going to completely go away though.

it did made my rpm a litle faster but, still very rough idle w/ a big cam.
