I have a 2003 Pontiac Grand AM and it always kills when i`m backing out, go to slow down, or make a complete stop. What can be causing my car to do this ? I`ve taking it to numerous mechanics and no one can seem to find the problem with it.
I have had my '03 Grand Am SE1 since 2005. It has been a good car, but I have had to replace the fuel pump. Would loose power on excelleration and finally died. Replaced the pump and its been fine. However I have a leak in my windshield from a bad replacement job and now my dash is folding up, cracked, and shrinking. If anyone knows where I can get a replacement, please email me. email@example.com
