Engine Performance problem
1998 Buick Century 6 cyl Front Wheel Drive 104, 00 miles

Car was hooked up to a code reader at Carquest and came back with a P0305 cylinder #5 misfire. Engine light flashes.
Question is, if/after I change spark plug and wire, how do I check the coil pack for failure?

A misfire on a specific cylinder-check the plug/compression and injector for that cyl.

I ended up tapping on the #5 Injector, and must have cleared a piece of debris, as the car is running great again!
