Question about 1999 Buick Century
Okay, this sounds like its misfiring, the engine light is on because the computer sees a problem, if you have the computer scanned it will tell you where the problem is, for example it will give a code and say cylinder 2 misfire.autozone will scan for free, if its a misfire i would start with a tune up , spark plugs ,sparkplug wires and air and fuel as needed, then see how it drives from there, the light can be cleared at autozone also, if it still picks up a misfire then depending on the cylinder you may have a bad coil pack also, there are three packs one controls two cylinders so depending on the cyliner misfiring thats the coil to replace, they should be labeled but if not just follow the wire to coil from cylinder, they are as follows, rear cylinders from left to right are cylinders 135 the front 246, hope this helps.
