This is really starting to bug me. I've got a 1995 Grand Am with the
3.1 V6, and the Check Engine light is on about 50% of the time. I've
had a mechanic read me the codes, but there were too many to isolate
the trouble. I've changed the Plugs and wires, the EGR valve, the O2
sensor the temperature sensor, the MAF sensor, replaced the radiator,
water pump and thermostat. Still comes on.. I wouldn't worry alot
except when the light's ON, the car will overheat... Only while the
lights on... I've checked the Electric fans, they come on at the
right temp, I'm at a loss... It performs perfectly, never a sign of
troubles. I'm sure it's temperature related, as it seldom does it in
the AM, while the outside temp is cooler. And the overheating, is
while sitting still, it won't overheat at hiway speeds, only sitting
in traffic WITH the light on... Any Ideas ? This has cost a small
fortune already, and the "Brain" is still a dealer item, so I'm real
reluctant to swap that out at this point. The car only has 94,000
miles, and compression is perfect. Fuel Economy is still really good
as well...

How do you know its overheating? Did you put an IR gun on it?
Without the codes we really can't say much.

I own a 1995 3.1 v6 pontiac grand am also and i swear to god my car has the
exact some problem your car does. my car over heats in traffic and my check
engine light always comes one for no dam reason. when i finnaly get home
from work and turn my car off, i can restart it and the light will be out.
my car does not get hot at night. my car has 92,000 mi and ive allready
replaced fuel injectors, my windows have come off track, my heater core
recently exploded on me and only my high beams work because something is
wrong in the steering wheel. Now let me tell you i take verry good care of
my car but if you really want to know what i think. I think its about time
we get new cars.
