Default 98 Pontiac Grand Prix

I just got a new engine put in and the engine light keeps coming on. The
last time it kept coming on it the shop kept resetting the lite but within
5 weeks the engine blew a hole or rod out it. I just want to avoid the
same thing happening to this engine. The cooling system has already been
replaced such as: radiator, water pump, hoses, oxygen sensors (both of
them. Any suggestions?

What lite comes on, pray tell?, if it is the check engine have it scanned
and post back the results, how could we possibly know what " a lite" coming
on is?

from reading this newsgroup it seems that you may need to hook your car
up to a diagnostic scanner to get the error codes.

The mechanic that did your new engine should be able to do it. The
codes will tell what the symptoms are.

If you are driving around with the red overheat light on you probably
will be needing a new engine. A new radiator and pump won't help much
with no coolant onboard.

P0420 is catylyst effiicency, which can be caused by too lean a mixture, bad
cat, bad sensors, this code requires extensive diagnosis to pinpoint.
