Simultaneous error codes
What would cause error codes "32" and "52" to simultaneously occur after 20-30 minutes of driving. I have cleared them and verified several times, no errors until the check engine light comes on after 20-30 min.
I have a 383 TPI with a custum chip. This situation began after the rebuild and new tune.
Any and all help or suggestions for trouble shooting is highly appreciated.
Thanks,
Jim

Re: Simultaneous error codes
Come on guys, I'm at least hoping for suggestions before I go replace everything.
I have a 1991 computer with an custom chip. Is it the prom?, MAP?, EGR? Alomost seems like a open-loop / closed-loop thing because of the time. When I restart the car the check light is off.
Again, I appreciate any and all feedback.
Thanks!
