My Buick’s rpm gauge goes from working just fine to 0 in a matter of 20min. The car jolts a little bit when this happens and used to turn off completely while waiting at a red light/stop sign/idling. Can someone help me figure out whats going on? Ive replaced the following: Spark plugs/wires, fuel filter, serpentine belt, MAP sensor, Battery (brand new and 200$), gasket seals, oil change. Thanks!

When it “goes to 0,” does the engine shut off, or does the car mysteriously recover and keep on working? Could it be a faulty ignition switch? My Accord used to just randomly turn off while in the middle of driving, and it took me a couple of months to figure out my ignition switch was bad. I replaced the ignition switch and things worked perfectly since!

Can someone tell me why my 2000 Buick LeSabre speedometer not working RPM and Signal lights
