Ok. I have a buick lesabre 1993 not sure at the moment how many miles are on it, but I think it's over 100,000. It drives, but only if you ever so lightly push the gas. If you put any kind of pressure on it at all it stalls. Also, I noticed that when it is running there is no flow from the hose that runs from the thermostat to the radiator.

Sorry for the late reply.

You need to see if system is running rich or lean. Check proper fuel pressure. Give it a tune-up. As far as your thermostat, replace it. Can you tell if circulation through radiator. Be careful on a hot engine.

Check for applicable trouble codes. Your obd1 so you should be able to check some codes, yourself. To check codes, use a jumper wire at the A & B terminals at the datalink connector. Turn key just till the dash lites come on, no further, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
