[ekjonjon]

Hey guys I have a 2002 civic ex single vtec 1.7. Out of no where 3 weeks ago it started drivin weird now the check engine is blinking and wen I checked it, it said random cylinders misfiring. Funny thing is if the weather is over 32 degrees it drives fine, but if its colder than that it will misfire and drive like crap... Oh but in the cold if I put dry gas it drives fine till I turn it off and start it up it goes right back... Please help me figure this out guys any suggestions post em. Thanks

bad coils brother ..and if your cel is flashing thats not a good thing ..deff check what codes the ecu has

If the light is flashing that is telling you that is the misfire usually under a load. I see this a lot with theses motor in the winter usually the issue Is the poor quilety fuel they mix up for the winter. They as more additives to the fuel for winter and some cars are affected by it in different ways. You can run a high grade gas or I have good luck with a bottle of Lucas fuel injectors treatment help and works the best. Also if you have not done a tune up recently throw some freah plugs in it. Good luck
