I have a 1993 Ford Taurus SHO, and when its cold out and i start it for the first time, it almost stumbles, or bogs. Like when i get on it a lil bit, the car jolts at around 3500 rpms. I also noticed when racing a BMW 325i when my car was a lil cold, that only when its cold, it has absolutley no power after 5k rpms, any ideas? Thanx Tom 1993 MTX
