I have a 1995 Chevy G20 Sportvan with a 5.7 liter V8 engine with about 62k miles on it.
It just started running very rough and the check engine light came on.
I got the codes from it which appears to be 12 and 32.
32 looks like it points to the EGR and MAP circuits.
Any suggestions on the best way to procede?
Should I change out the EGR valve and MAP sensor?
Thanks Very Much
