Speedometer and warning lights dance when under load or asked to accelerate quickly.
This has been an ongoing issue for 10 months. The dance starts with ABS light then speedometer needle dances up and down, no fuel symble comes on, and any other warning light on the cluster. Sometimes it misfires, once the service engine light came on and it shut down. Temp fix for that was computer fuse replacement. Replaced front wheel bearings for abs sensor., speed sensor on rear end, swapped out speedometer cluster. Then put New ignition switch in. Drove under a load for 1600 miles and as long as I do not romp on it the gauges never come on. Changed speed aensor twice. No fix. Ready to put a new computer in and fuse box under hood. Any better ideas?

the number 1 place to start, check your grounds! Troubleshooting can start at the beginning, the end or the middle of a circuit. The beginning is the power source, the end is the ground. You have been chasing rabbits somewhere in the middle. Throwing money, time and effort at an issue rarely works. You know the power works, so start from the other end.

As others have stated, you have a ground issue that becomes apparent during pronounced vibration scenarios. Pull one off at a time and clean with 240 grit emery cloth. Locate every single ground point and process accordingly.
You should also inspect the battery cable for any crud and/or corrosion that might have formed under the sheathing. You might be experiencing a voltage drop situation.
