Intermittent Acceleration Performance
I have an '07 a/ 6sp Auto. Experiencing intermittent wide-open acceleration performance. It never had bad accel, but sometimes it will pull (like I assume it is supposed to do) all the way to 7,500 (Auto red-line) with "push back in-your-seat" performance. At other times, the engine seems to flatten out around 5,500 and struggles to accelerate, especially in the taller gears (3rd).
No detonation, no backfiring. 26,000 miles now. K&N Air Filter element. No MIL lamp. Strange thing is, during extreame cold (under 25 deg F), the engine performs the best (last night felt like I was steering a turbo'd engine).
I'm wondering if a Knock sensor issue. I use premium fuel and keep track of where & when. No correlation with this issue.
Any ideas?
Also, the extreme cold brings about a seperate issue - my steering wheel seems to be pulling left or right as I drive down a slightly bumpy road. Don't notice in the warmer weather.
Thanks! Bill

I don't buy Kool-Aid
Rotarys like the cold.
As for your sometimes WOT sometimes no WOT, well it could be one of two things.
One you need a new Engine or two you need a new trans.
Also I had this prob in my old AT four speed. I was on the free way. Tryed for WOT and it just would not go. Kinda scary if you ask me.
You cant floor it in a AT you have to ease into it then try to floor it. But if your on the freeway and trying to pass you should not have this prob right? Well thats what I thought.
