I have an 03 cadillac Deville base sedan and I want to know what is causing two problems that I have with it. One of my problems is that the acceleration is a bit slow when I pin it and sometimes hesitant. It rides really good otherwise. It's only hesitsnt when I floor it after im alreadyt going around 40 mph. But for 275hps I feel like it should have a better and faster kick to it. Another problem is when I'm traveling down the highway around 65mph or higher it will jerk every once in awhile. It never jerks when I'm going 62mph or lower. Other than these few things it ride excellent. I also have po101 code and po410 code. I just replaced the mass air flow sensor for the po101 code and I'm having same problems. Not sure if it's the catalytic converter, vacuum leaks, etc. The idling and coasting are fine.
have the same problem?
