blind_elk Posted June 18, 2007 Share Posted June 18, 2007 S1 runs an ignitor module? When they get a bit old, they tend to start breaking down when they get too hot.

Luciano Posted June 20, 2007 Share Posted June 20, 2007 You can check your coilpacks very easily. Remove the plastic cover over them. Then go for a 'spirited' drive at night when it's dark. Try to recreate the situation where the engine does its bad thing. Then pull over and pop the hood and stick your head in over the packs. I had bad packs, and when I did this, I could clearly see the spark arcing on 3 or 4 out of 6. Bought new packs, and 100% fixed.Just easy to check this first since it's such a common thing in 'lines. you should try what sl33py suggested in another thread in this forum. pretty easy test theory for your coils... at the end of the day, its all mechnical/machinery.... solutions exist! calling it a rusty bucket / shit box wont pin point your problem... does your turbo still boost up under acceleration?

Firstly when everything went wrong it was a full miss fire like it had droped a full cylinder so i got the injectors cleand and 5 and 6 replaced after that for about a month it was perfect it was idling and runing perfect all of a sudden it started missing again and noticed the 6th spark plug was shot iv replaced all spark plugs after that the missing stoped but it wouldnt idle very well and weirdly enough after when i let the car cool down after work just say when iv gone to sart it again it starts missing but only for about 10 seconds, so iv been trying ta locate witch cylinders missing bye disconecting the packs while its missing and so far iv replaced one coil pack and still having troubles (so yeah iv had a basterd of a time) Link to comment https://www.sau.com.au/forums/topic/173182-help-dropping-cylinder-rb25det-series1-r33/#findComment-3190234 Share on other sites More sharing options...
Race_Bred Posted June 20, 2007 Share Posted June 20, 2007 could be a blown head gasket, it could be running like crap due to water leaking into your cylinders and causing the missfire on cold start, try pulling the spark plugs out one morning before u start it and crank it with no plugs and see if water flies out of the plug holes Link to comment https://www.sau.com.au/forums/topic/173182-help-dropping-cylinder-rb25det-series1-r33/#findComment-3190252 Share on other sites More sharing options...
