EJ25 Coil pack problems

Post by Volare-Q17 » Tue Feb 05, 2008 9:35 am

Hi Guys
Having a little gremlin in my system. I went up the shop the other day, car ran perfectly. Stopped, went into the shop, came back out, started the car and it was only running on 3 cylinders. After getting RACQ and a local Mobile mechanic out, all seemed to point to a coil as there was no spark on one cylinder.
Luckily, my Uncle lives near a Subie wrecker, so he grabbed a coil pack and brought it over. Fitted it, started it 4 cylinders again ..... sweet :)
Next morning (today) took the son to school, started on 4, but after about 3klms it was missing a little bit. Stopped at the school, walked him to class, came back, started it, and back on 3 again, and seemed to run rougher and rougher all the way home. Phoned my main mechanic who said it may be a faulty coil pack. Before I go through all the dramas again, has anyone else had this issue and does anyone have any ideas on what it may be or whats causing it?
I am a pensioner, so when you spend your last dollar on a coil pack and the problem persits........... ya kinda get a little discouraged with Subies.
Mine is a 97 RX 2.5 AWD wagon as seen in my avatar (i think)
Cheers and thanks in advance

Yes they are not always reliable my brumby has been through 4 in last 9 months. Mine would miss at higher revs/boost . Also try swapping coil packs with another cylinder if prob goes with pack its the culprit. Thats how i have fault found mine in the past Also try checking pressure of fuel rail, could have a partialy blocked hi pressure filter ($8)etc. One other thing to check is that injector is working correctly Could need cleaning etc. Vavles closing up can cause similar issues
eg gets worse the longer its driven.

Check out the fault codes.
So many optioins not enough time or money:confused:
