Hint: Use a descriptive title for your new message
If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

I had my vehicle throw a P0300 MULTIPLE MISFIRE CODE. Started running rough and check engine light came on. Found the Fuel pump relay sticking. Replaced it and everything was fine for about a week. Then the issues stared again but not getting any codes stored in the DME. Anyone have this same issue?
