Contour Enthusiasts Group Archives Forums General Troubleshooting Running Cold and Choppy Power

My 98 tour with 2.5L V6 MTX, on the highway runs very cold. I have just recently baught this and am not sure if this is normal. By very cold it just touches the N on the temp guage, it rarely ever goes past half way on the N. I drive about 120km/h to work and back 45min trip each way. Also when I give it a lot of gas mainly in second and third when it hits about 4500rpm it chucks a little its almost like it loses a little power for a half a second, its choppy??

Thanks in advance for your opinions!!

I have noticed the same thing in my 4 cylinder contour. It runs cold but the car still feels normal and still has the power (I said power HAHAH) it usually has. So could there be something wrong with my car?

THanks

Searched and found the fix. I need a new sender.

do you have a check engine light on? The last Duratec tour I drive (SVT) that did that, it had a stickey IMRC. I know what you speak up... There is something in the duratec motors called "Secondarys" in a really basic sense, they open at about 4000 RPM's so you can have a more consistant power curse, if they didnt open after 4000 rpm's the engine would feel like a dog, very slow. I drove a CSVT with a failing IMRC, it would hickup right at 4000 rpm's every time you would get up there.

Some more information is needed though.. how many miles? Do you know when the last tune up was performed?
