my 1992 grand prix has a problem, the check gauges light come on and stays on, and sometimes it goes away. all the gauges are working fine, what's causing this problem and how can i fix it? also the car hesitaces on acceleration..

Probably an Oxygen sensor. How long has it been since the car was tuned up (plugs, wires, etc)? Get a code reader and see what codes were set by the computer and that will tell you what is going on. This is just basic advice, sorry for the lack of detail.

we did a new tune up including plugs, wires and filters. i check for codes but they were none.
the car idles fine but when i press the gas it miss like it needs a tune. (some time not all the time)

You might want to check and make sure none of the plugs were damaged during their install. An intermitant light and stubbling during acceleration sounds like your missing a lot. Does the computer maintain a history file of codes and misfire data (might be an OBDII thing)? If so, check them out and see what you find.

Miles? Do you have any loud noises under the hood? I've seen a car do exactly what you have listed and it ended up being a cracked exaust mainifold.

no! no noises.. the car has 151,000 miles and it idle
smoth. the check gages comes on and stays on or goes off.. and when i press the accelarator it hesitates
(misses) but not all the time, all off the other time
runs fine. i try taking the codes out but there are
none..
