A few cars on board now with poor running cars and bad cats. Do u think a 96 car with 140k miles and no codes would benefit from new cat? I did have leaky headgaskets for several yrs so I know coolant was fouling up combustion. I wonder if my cat really flows as well as it should? Did I mention that I cannot spin my tires? Never have. Car has always seemed to be down on power from day 1. And I have owned it since 2000.
Car just seems to fall on its face when I floor it from dead stop. Sort of goes "nope"! I have never driven another caddy so I have idea how it should run. Trac control? Haha. It never even tries to engage. Hell, I even have trouble spinning tires n snow! Trac does work than.
Maybe the thread title should be "gutless" car. I changed fuel pump 5yrs ago. Have put in 1 Fpr. Can't even recall when. Fuel filter is probably 5+ yrs old. Car has always run good but never really had good off the line pickup. Drove 2k Bonne ssei and I could spin those tires for 50ft. I am not blaming cat since I have no driveability issues or codes. I do have the Sts so I have 3.7 gear and crappy tires. U would think I could at least lay rubber.
