I was driving to work today, and my Check Engine Light, ABS Inop, and Check Gauges, were lightly flickering. They were really light, but kept flickering. Once I started driving on the freeway/interstate, They flashed once, stayed on for like 3 seconds, and then they shut off.. What could this be?

Its 95 Pontiac Trans Am?

 

I had a similar problem...... check the ground in front of the passenger side shock tower. Make sure it is clean and has a good connection

 

I will try that.. Thanks!

 

Like said check the ground

 

Let us know how you make out!
