COIL PACKS?
Hi, need to replace coil packs, well at least i think i do. my93 wrx comes on boost and when revs are around 4k - 5k seems to die/splutter. have few mods and run pfr7b plugs. theres no action on the knocklink except when spluttering happens, then we have the christmas tree effect. anyway, is a subaru dealer the only place to get these or are there any other alternatives?
i run a scoobyecu(15.5psi), decat exhaust, panel filter, uprated fuel pump and reg. thanks for any help.. |
just replaced mine mate on my 94wrx grade a breakers £35 or they r about £90 each brand new
|
ray,
did u have similar problems as to what i have described? |
I had my coil packs replaced on my MY93 WRX, it would run fine one day then all of a sudden it would be like a tractor spluttering away, I had all 4 changed at once at Prosport and it's run fine ever since

Remove the coilpacks, pull back the rubber sheath on the end of each coilpack and check to see if there are any hair-line cracks/fractures in the ceramic on the ends - If there are any they are likely to be causing a degradation of spark under boost conditions. Also with the coilpacks out check the plugs ;) What gap you running?
Cheers |
gaps on plugs are 0.8
will check coil packs tomorrow before i order new ones. what should the gap on the plugs be or are they right? cheers |
They are normally recommended to be 0.7mm on PFR7's ;)
Cheers |
ya its sounds the same as you had but i have changed 2 of them cause only see 2 broken but now it flies through the gears but when i get to 100 in 5th at 5000 rpm it s hesertant and take sages to pick up
so i dont know whats wrong with it now anyone know |
replaced coil packs with four new ones today and a new set of ngk pfr7b's gapped at 0.7 for good measure. everything now seems fine. :) thanks for all your help.

Nice one happy driving
