 Help, Bad Hesitation in my 1999 Mustang Cobra
Hey i just got a 1999 cobra like 3 weeks ago with only 11,000 miles on it. So the other day i decided to really open it up for the first time. I was in third Floored it and at like 3800 rpm, the car just hesitates, and falls flat out on its face. i couldnt get it past 3800, cause it just started to slow down, but i can get higher up in first and second. The guy i bought it from though never really drove it, and it just sat in the garage. Any ideas on what could be wrong?? |
