My Check Guages light comes on intermittantly and my Service Engine Soon Light comes on. I had the computer codes checked and nothing comes upwrong. Any Suggestions?

The Check Gauge light would be intermittent, Only if the oil pressure go to 0 psi or coolant temp jumps to 260 deg or volts drop or over volt will the light come on. The service engine soon light with no codes could be one of many things. Will need lots more info to help with that one.
