1985 Coupe Deville

First I would like to say this site is great,especially for those who cant afford alot of trips to the mechanic.Just recently I had a new battery installed in my car.When I started the car up I noticed the gas mileage formula had changed from gallons to liters.Can I change it back,if so how?Also sometimes I start to accelerate and it kinda tugs,almost like its not getting enough gas.After getting it going a constant speed its fine.Until I have to stop and then go again.PLEASE HELP ME.THIS IS MY KIDS AND I ONLY CAR.

Hmmm I am not sure on the metric to standard thing... I will check on that. As far as the tugging... might be time to have that Throttle body cleaned!!! all of it!! If it is packed full like mine was it will make all the difference in the world.

Isnt it carburated and it not fuel injected? But whatever it is its always good to give everything a full cleaning, you could use carb cleaner but it wont do the best of jobs. With the gas thing, disconnect the positive battery cable and put it back on. Maybe it will reset something again.

There never was a carb'd 4100. And all caddies that werent a limo got the 4100 in 85.

Hmmm I am not sure on the metric to standard thing... I will check on that. As far as the tugging... might be time to have that Throttle body cleaned!!! all of it!! If it is packed full like mine was it will make all the difference in the world.how do I do that and what would you suggest for me to use for that?
