1999 Bonneville

[davidjsena]

Slow to accelerate, runs rough at lower RPM's, stumbles on take-off. Scan says crank position sensor, random misfire and O2 sensor issue. Anyone with similar issues who may have a suggestion?

Look up the codes you are getting at this site and follow their suggestions to correct the issues. You may need a new crank sensor or have a bad wire harness, same with the O2.
