i just put in some mac equal length headers in my 5-0 to complement my off road H and flowmaster mufflers..but ever since the headers were installed a weird thing has happened. (my car is an automatic) where the car shifts into the next gears has changed....it doesnt even get out of 1st til around 40mph...and the rpms never red line or anything like that so how is this happening? is this bad? please give me an explanation...if i didnt give enough info please ask. thanks a lot

oh and the car shakes a whole lot now while idling can that be minimized?
 
I was gonna suggest checking that your VCR was plugged in and that the time was not flashing 12:00, until I checked the link. Good link.
If it is a vac you will start running better right away.

Make sure the DVD cables are routed properly too. :D
 
That pic is for a TBird, for a stang it goes under the TB throttle activator. The stock grommet is plastic and it gets cooked and breaks/cracks and the TV cable falls out and your tranny burns up very quickly. That is why there is a service note on this.

Good Luck, Don
