hey have you tried changing the fuel filter
i have a buick regal and love it you probably got bad gas.
I have a same problem. Answer: I had the same problem and it is digital and not a cable. bad news is that it is in the transmission and that's what fixed mine.
Most likely a bad sensor
Could be a bad thermostat or heater core
with our 98 regal the resistor type key was bad, try your second key if you have one
if it has a crankshaft sensor that's bad
Could be a bad thermostat or heater core
Clogged air filter, defective O2 sensor, clogged catalytic converter, bad plugs and or plug wires, poor driving technique to name a few possible causes.
Yes
Depending on the year, the Regal could have a relay to control the high beams. Check the distribution box under the hood to see if there is a bad headlight relay.
Flasher is bad. to replace it it is under the dash at the back of the steering column.
Sounds like a bad cable
