why is that i always change my dizzy? now i put msd dizzy less than a yr then my car got stuck up. my car stall in freeway/fastlane then somebody told me to change the cap, now its running again..afraid that it might stall again, happened twice... is there too much electricity goin on with my car??? b4 it has a cel eld.. someone fixed it, then now it says cel code 1 and just bought a brand new o2 sensor, now my car is idling 500 to just above 0 when i stop on a stop light... should i need an engine rebuild? btw, its jdm itr on eg..
