A couple of things come to mind, first check this bulletin and see if it pertains. It also states that you would have lights coming on:
#PI01574A: Intermittent Erratic IPC Sweep With Possible ABS Or SIR Lamp On - keywords cluster fluctuation gauge head instrument IP light MIL panel - (Feb 20, 2009)
Subject: Intermittent Erratic IPC Sweep With Possible ABS or SIR Lamp On
Models: 2000-2004 Chevrolet Venture
2000-2004 Pontiac Montana
2000-2004 Oldsmobile Silhouette
This PI was superseded to provide a clear diagnostic procedure. Please discard PI01574.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Some customers may comment that intermittently, the IPC gauges sweep erratically (not as in WOW test) and the charge, MIL, ABS & SIR indicators illuminate on the IPC. Typically no DTC's are set. This condition occurs briefly and there is no pattern as to when (hot, cold, fast, slow). This may be a result of a loose connection to the PK3/Theft Module or the PK3/Theft Module itself.
To correct this condition verify that the PCM/PASSKEY/CLUSTER fuse and the PASS-KEY fuse for the PK3/Theft Module are fully seated to the IP Electrical Center. Verify the integrity of the wire crimps and terminal contact for these fuse(s). Inspect the PK3/Theft Module connector. Verify there is adequate pin drag and crimp to the wires in this connector. If there is no trouble found, replace the PK3/Theft Module at steering column as needed. Retest vehicle.
Another concern is maybe the cluster itself is acting up. What happens when the needles stick, when do they resume operating? A simple test is performed to condemn the cluster, a gauge sweep test. It is performed with the use of a scan tool, though. As far as I know, an aftermarket scan tool is not capable. I may be wrong.
