1988 buick Century backfires so hard it blows the muffler apart?
A backfire in the exhaust system is usually the result of a rich mixture ( too much fuel ) being supplied to the engine. It can also be a result of a timing/ignition problem. Does the vehicle run ok at idle? Is the check engine light on? If so, have the codes scanned for any problem areas that may be causing a rich mixture
What can I do to save gas on my 1988 Buick Century
Drive slowly, don't over rev the engine if you don;t need to.
Check the tyre pressures also.
Take anything out of the car that you don;t need with you as more weight in the car equals more fuel used to move.
Finally, any roof bars or boxes on the outside that don't need to be there can be take off, this will help with aero.
Other tips might be to cruise behind another vehicle on the motorway, just not too close and also don;t bother with cruise control as this tends to use more fuel than a careful accelerator foot.
Also keep your engine serviced and if possible run some engine cleaner through the system. Airfilter needs to be clean too or it will be starved of air and need more revs to work
How to fix my gas gauge on my 1988 Buick Century
Could be a number of things.
The fuel sender could be at fault not sending any voltage to the gauge. One way to check this would be to find the signal cable under the rear passenger seat, short them together and see if the gauge moves.
If not that then the gauge could be borked
