Default 1985 error codes

Ok,

So I finally got around to pulling the error codes.
I'm getting 32 and 43.

Any ideas on where to start looking? The codes go away after I turn car off.
Only to have light come on next time I use it. They only appear after light acceleration, seams to have a little stumble, light comes on, and then runs fine, other then SES is on.

Thanks,

Ok,

So what's the best bet, replace spark module, and EGR valve?

don't care about EGR if you haven't to pass smog test,most guys here don't run egr in their cars...this the reason why i don't posted any schematic of 32 code....
Test your ESC and then replace if need...
