i just finished the 2nd gen coil setup but the car is idling weird.
i did the complete setup as the threads explained . it took me a while to understand it but i finished it last night. i drove it and felt a big difference and then the car began to idle a little weird like it wanted to stumble and shut off.i drove today in the morning and it drove fine until in the aftrenoon.it felt like something was holding the car back.please help.just to be safe i will be driving my other rx7 until i figuere out if i did something wrong....
the 2nd gen coil pack had 2 wires one coming from the ballast resistor to the negative side of the fc coil. the other wire was coming from the ballast and was hooking up to the power side of the stock leading ignition coil in my engine. then i proceeded to hook up the negative wire that ran to my stock fb coil to the negative side of the new fc coil. i then removed the T.....T1....T2 WIRES..i went ahead and rerouted the wires as the thread on the board stated..
Now pull the lines going from the distributor to the leading plugs off the distributor. Move the lines going to the trailing plugs from the trailing spots on the distributor to the leading spots. and attach them to the new coil.
I WOULD APRECIATE IT IF ANY BOARD MEMBERS who HAVE DONE THIS SETUP COULD DONATE A FEW PICS OF THEIR WIRING OR OF THE COIL hooked up...ANY HELP IS APRECIATED.. i looked at the pics on the board but im slow sometimes
THANKS.....

i did the same exact set-up and like u i have stumbling probs,but they only happen when i brake.keep in mind it didnt do that untill i direct fired. try messin with the timing. lead and vacuum trail. everyone fogets the trail. i ended up just living with it at 1200 rpm so it woulnd die. sorry, no pics though.

Yeah, they say you have to adjust the timing about 10 degrees more advanced as this mod changes the timing. Have never had a clear explanation as to why though.

maybe this will help. my writeup The directions might not be that clear but maybe it'll help. Theres some pictures in there too.
I personally never had that problem and never had to adjust the timing. It really shouldnt change as far as I understand it (in theory that is). Hope it helps.

veryy nice write up inuisses. the first time i tried the mod, it totally backfired..literally. found out the coil i took was dead.. second time i tried it the wires were crossed and didnt give any feed back and started running only on trailing. so just be careful and go over the wiring..
my two cents

The timing change is only with the TT. If you do the regular 2GCDFIS, like inuissius's write-up, there is no timing change. As for the problem, check for spark on the leading. It sounds like maybe it quit firing. Maybe some wiring came loose or the leading ignitor died on you.

The 2nd gen coil upgrades (either this one or the TT) replace one of the coils with the 2nd gen coil. The trailing 1st gen coil stays in place. What FBII is taking about is yet another ignition upgrade where you add a second 1st gen style coil and ignitior to the leading ignition making a total of 3 coils.

ooops, yes, i meant to say "not using the stock 1st gen Leading coil" lol.
addict is right tho, the dlfsdidifsifuosufdisease is adding another stock style coil to the mix. oh well, do the 2gdfis and rock on.

this is what happens..
the car starts fine.so i know that the coils must be wired up fine ( fc ) coils..i can drive the car but then at a stop the idle begans to drop for no reason, not always but it when it does it gets as low as 700rpm.then the cars idles weird almost like when a car equiped with a bad throttle position sensor would.you guys think i should check timing??
also is the timing procedure the same even after moving the ignition wires around and changing the coils????
please help with any tips...

so just to clear up...
there are small wires running to the stock coil, a positive one and a negative one. take both of them OFF the stock coil (you can get rid of the stock coil for all it matters, though I would leave it in there just in case your 2nd gen one fails on the road)
you then connect the postive wire to the positive terminal on the FC coil.
then connect one end of the ballast resistor to the negative terminal on the FC coil and the other end back to the negative wire that originally ran to your stock coil.
and if you have already done all of this right, then I dont know what your problem could be, aussiesmg may be on to something with the shutter valve. Just check to make sure it's your new ignition system by hooking up your old coil as it was originally, and see if you still have the idle problem. If the problem is still there go to the shutter valve.
it doesnt sound like the FC coil isnt working or is not connected though, because I did that at first and it will idle ok but revving it higher is where you would find a problem without the leading plugs firing.
Good luck
