You will probably get a more accurate response based on the year of your specific car.
Unfortunately, when the new site software was installed several months ago, we lost the vehicle info that appeared under your avatar/screen name. Go to your profile, click the "About' tab, and fill in the vehicle info - year, model, engine, trans.
Why not add the info in your profile, so it shows up automatically below your screen name. That way you won't have to type it in every new thread, and people will not have to ask you for the info if you forget.
