one plug keeps fouling
i have a problem, every month or so the top plug on the front rotor keeps fouling.
i have 1600cc secondaries and 850cc primaries. the car idles and drives and boost perfect. but for some reason that one plug always foul out. im thinking the coil is a little week..

yes the plug is getting spark. once the plug fouls the car bearly idles and dies, but as soon as i change that ONE plug it starts up like a champ and runs perfect for another month or so, i chaged the plug 6 times already and it started perfectly everytime after i chaged the one plug.
could one one of the 850cc injector be dumping a little more fuel at idle the the other one wich might cause the plug to foul after sometime, i dont think its a harness problem because it starts right up after replacing the plug... but icheck it anyways. thanks.
also what should my a/f ratio be at idle

okay i replaced the wires on the car since the old ones looked old and i dont know how long they been on there.
also the plug that keeps fouling is the lower sparkplug on the front rotor not the top one sorry for the mix up

okay so last night i was leting the car warm up to take it for a ride and 6 mins into warming up once again the idle dropped and sounded like i was running on one rotor!
so i took out that one plug on the front rotor i beleive its the leading plug wich was the bottom one, the spark plug was very black in color *rich* i assume. so i took out a brand new plug installed it and boooom the car runs fine again. it will run fine for anothe 3 weeks or so and then foul again beacuse this is my 7th time replacing that damn plug, all the other 3 plugs looks ok not too black in color and they never fouled.

if the wires are good/new then the coil would be the next step.
11.2 is rich for idle though, it should be at least in the 12's
