After the car ('97 328i) was parked in the parking lot for 12 hours
(normally it is parked in the garage) in cold temperature, when the
car was started, the whole car was shaking (similar to misfiring)
and after a minute or so, the CEL came on. The shaking continued
on, wife drove the car home like that.
I started the car in the morning, same story. Misfiring, CEL came on.
Took the car to the Autozone so that they can read the codes.
Code 1 - P0302: Cylinder 2 misfire detected
Code 2 - (forgot the #): Fuel Trim Malfunction in Bank 1.
By the time I drove to Autozone, the misfiring stopped; the car ran fine.
The autozone employee reset the check engine light.
I put in a can of Fuel Injector cleaner and filled up the tank with 93 Octane gas.
Since then, no problems observed. What happened??
I know things don't just fix by themselves; Symptoms might show up again.
I will check the Spark Plug and Ignition Coil Pack on Cylinder 2 and see
if I notice any fouling on the spark plug and cracks on the coil pack.
