I had a similar problem, it was the o2 sensor.Hey, I am new to the Caddy world and to be honest I have like them for all my life really. so finally get one and not doing my research I got this one... has only 94000 original miles... all the bells and whistles but
it is having one problem. Power on the takeoff. When I press the gas it goes nowhere fast and then gradually catches back up. I have had my mechanic tune it up when I first got it and after I thought it was the tranny.. took it to Aamco and was not the Tranny.
Does anyone have any suggestions as to what it could be?
I am thinking of engine swapping. What would be the best fit with a good amount of power?
A popular swap is the LT1 and 500. I'd go with the LT1, plenty of power,and not that hard of a swap from what ive heard.
