1990 speedometer problem
Noticed driving the last few days that the digital portion of my instrument cluster is acting up. Works fine, hit a bump in the road and it becomes garbled. Hit a bounce again it clears up. Don't really know if it's coincidence. Last night I parked and it was fine. This morning I started it and it was garbled again (I'll attach pic). Now it's not clearing up. I can't run the codes because I can't read them in the cluster. Could this be a grounding issue? Speed sensor? I did get a check engine light on Monday but it went out and never came back.
Any suggestions on troubleshooting this would be great. Thanks

I thought it could be but wasn't sure only because I couldn't get it to come back today. Tonight it came back for about 10 minutes and it's now garbled again. I don't know where to begin but i assume I need to check all the grounds. I was hoping to find someone who had the issue and could give me some guidance. Thanks again
