i fix the p0303 and p0301 but still have p0300 and p1380i changed my opti spark from auto zone and didnt make a diff but a friend of mine gave me a used o.e.m optispark and it pics up way better but still have small miss plus when the car gets hot it misses a little harder but it still drives better with used o.e.m i have been doing research and found that could be something dealing with voltage or (vtc)or (pcm) do any one have any ideas or any one in d.m.v area that can diagnose problem and actuly tell me the real problem
