  • 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.

Car has 25k miles, last few months started running rough for first 20 seconds, until speed drops. Anyone else find this happening? Any suggestions? Afraid it would have to be at dealer for weeks if they take it serious, since it only lasts 20 seconds each cold startup. Did clean throttle body and mass aairflow sensor, no change. Stopped there.
Thanks
