I have a 2007 chevy impala.i got a diagnostic test and it had code p0720 a updated speed sensor. I changed that however my car keeps stalling and when it stalls it reads speed limit 107 and cuts the acceleration down.There are no check engine lights or anything on the dash board lit up. I can still drive the car but I dont want too.They did say there were metal shaving in there Help me please.Im tired of paying for things I dont need.

There is obviously still a problem in your speed sensing circuit. When you reach 107mph in the car, the ECM cuts fuel to slow the car down. Obviously if it does this when you are at idle (incorrectly assuming you are doing 107), its very possible that the car stalls because it isn't getting enough fuel. What part was previously repaired?
