My sister-in-law has a 2007 Suzuki Forenza, and she has had many problems with it. It's been running rough for awhile and she recently got the spark plugs replaced. That helped some. But right now she has a problem where it keeps overheating. I assume she means the needle goes up to the H and stays there, then comes down then goes back up. She texted me the other day when she got to school and said it freaked her out b/c it overheated almost the whole time. The other thing that she said it is doing is when she first cranks it up and while driving off slowly she has this jumping feeling. I haven't had a chance to ride in it to get a better description, but does anyone have any ideas especially with the overheating? She is going to school so money is kind of tight. She has taken the car to a mechanic last week and he couldn't find the cause of the overheating. Thanks for the help!
