Ok I have a 2003 Cadillac Deville base sedan and am having two problems. First of all I have two engine codes, one is p0101 and other is p0410. My first problem is my acceleration is kind of sluggish. Its takes longer than what I think its supposed to take to get my RPMs up. Ill push the gas pedal down quite a bit (not all the way but pretty far) and it takes the RPMs awhile to get up. It has 275 horsepower so I would suspect it would have more kick than it does. I think this is because of that p0101 code. This is the MAF sensor code and I replaced the MAF sensor with a brand new GM original Delphi one and the code still came back and I'm having the same problems. I brought it to Kheone, a GM dealer and they said the catalytic converter is clogged and is making this MAF sensor p0101 code to go off. I have researched this and this can happen. My air filter is clean, my spark plugs are good and theres a new MAF sensor and wiring is good also. I don't think there are any air leaks. My other problem is that on highway speeds like 63-73 my car will have a little jerk like it loses power for a split second and goes back to normal and then it does it again a few miles later. Sometimes its a little bit more noticeable jerk sometimes you can barely notice it. But if I go 60 or below or 74 or higher it doesn't jerk at all or rarely ever. I am not too sure whats causing this to happen. I was maybe thinking bad torque converter? Could it be these or something else? Can an expert mechanic please try to help me out!
have the same problem?
