My daughters 99 firebird has a problem while driving, the oil pressure and amp gauges bounce around and the car seems to be missing. No SES is showing. Tried higher octane fuels, and a new fuel filter. The car stubbles worse up hills. Any help would be appreciated.

Is it actually missing, those are known for coils dying

Yea, its missing, but there isn't any ses lights. And it seems to run worse up hills.

I would do a scan to check for codes. The check engine bulb could be burned out. Is it really missing with bad vibrations and all or just having a general loss of power? I had a clogged cat that resulted in power loss that was only really noticeable when you got on it or went up hills. I also had my share of misfire issues due to wires that had melted/cracked and were shorting out.

The ses light is out, I scanned it. Showed a misfire on the #6 cylinder. It was a bad coil pack. Thanks.
