[peterpan]

I have just change the egr valve and the o2 sensor. But when it get cold
code 13, 32 again, and I just change the map sensor. If it warmer the
errors seem to not show up.

I don't remember if the EGR solenoid on the '95 is vacuum or electrically
activated. having said that, I'd suggest you make sure that the vacuum hose
is not cracked or leaking if it is the former. In fact at that age, I'd
make sure that all the vacuum hoses are good since a leak in any would
reduce vacuum in others. Also, when you had the EGR valve off, did you
notice if the exhaust manifold or intake was plugged which could affect
proper operation?

Good luck.

Yes, the EGR solenoid is electrically on the 95. I check the manifod intake
is see. When I changed it I looked but not very closly to see if the was
pluged up. What confused me is that check engine light turns on when it
is cold out side?

Thanks for the help...
