rough idle solved read on
 

hello to all
ok last year i replace 2 ignition coils + all 6 plugs with ngk ones
i started to notice like a miss at idle and a little rought at times today i decided to check the plugs well the first 2 were nice burning light brown
the other 4 had dark stain like muck humm. well i decided to check the resistance on the rubber boot the 2 new coils were 1.98 nice 2kohm stamp on side well the other 4 were bad 2.4 to 2.6 meaning the spark plugs weren't getting enought spark and fouling the plugs a little bit.hope this helps others
enjoy

so you mean that there were 2 boot with ±2k and 4 other with 2.4k+ ??

you think it is the source of the miss idle or you replaced the "wrong" ones with 2k boot and now it is ok?


thanks
