Newbe ?\'s

Im new to the site, and I have just bought a 90 GMC suburban. I have a ses light that comes on at times when I accel. I pulled the codes and found a 32 and 43. Has any one ever had these codes and what could cause them? Thanks.

Code 32 is the EGR system, and code 43 is electronic spark control. Check the wire at the knock sensor, that could be screwing w/ it, or the knock sensor could be bad.
