Hello,

I have a 2001 Cadillac SLS with the northstar. I also have a 1996 eldorado with the larger northstar engine, more h/p. The 2001 SLS does not get the gas milage the 1996 does. Will cleaning the throttle body help with this problem? If so how do I go about doing this? The SLS has 73 K. the Eldorado has 62K. Seems like it's drinking the gas!! Thanks ellis479
