Hi, I have two engine codes for my saturn sc1 code #32 (EGR system problem) and #53 (info flag-ESC exceed max value)
Can anyone tell me what this means and if it is serious. Is it something I could repair myself?
Thanks!!!

Go to any parts store, buy a new EGR valve and put it in. You will need a socket set, they're held in by two bolts. No, your engine won't explode. It just effects performance.

the ESC problem MAY be caused by the EGR. sometimes removing the EGR and cleaning it will solve the problem, but a new gasket will still be needed
