Check the plug leads to make sure they go to the correct plugs.
Leading go to LOWER Plugs and it does NOT make a difference to which plug,but if you want to be correct then look at the coil and place the lead at the proper plug.
L1 is Front Lower plug,L2 is REAR lower plug.
NOW Trailing leads NEED TO BE SPECIFIC..T1 goes to Top FRONT plug and T2 goes to Top REAR plug(closest to Firewall by the way).
Again the Coil will say that.
That IS if you are working on an FC engine which I assume.

Ahh yes, **** doesn't work and i don't feel like learning how to fix it i'm just gonna sell it off to another sucker.......

Did you unhook the "rev counter" and see if the problem disappears since you said it started when you hooked it up
Have you compression tested the engine?
Replaced the cap and rotor?
Made sure your timing is correct?
