My Buick started having a rhythmic miss at the same time the engine light came on. I tried to access the codes but the OBD2 reader could not download any. Yesterday when I turned over the ignition, it let out (a short) what sounded like a backfire through the carburetor on older vehicles. I proceded to start the car at which point is ran smoothly & the engine light did not come on. This lasted about a day before it started missing & the engine light came back on. Please advise.
