just went through that with a 2003 la sabre buick with the 3800.
after long cool down it would start and run till it got to 156 degrees via the info center and cut off like someone shot it. Could repeat. Took long cool down to ran again. Spraying water on various modules did not produce any changes.
no codes... so.. replace the crank shaft sensor...book said that was probably the first culprit. Had to order the special bolts for pulling the pulley/damper/harmonic balancer off other wise easy.. But then.... found out it lost its programed timing points.... had to pull the battery for 5 minutes,,to get the ecu to go into relearn mode as I did not have the $2000 tester to tell it to do that after the css was replaced. It relearned its timing, as you ran it at idle for a few seconds and then wide open for 3 seconds... and then turned it off to force a rewire of the ecu... then... itran smooth, and at 156 degrees it cut off again. replace the spark module under the coil packs next. as that was next on the list in the trouble shooting book.. fired it up and but it died at 156 again,, but this time it threw a code saying the maf sensor was bad!!!!! replace the maf sensor and problem is gone... code cleared and everyone one is happy.
So... I suspect there were several problems.. but IF.... the maf sensor is unplugged, its supposed to run on a default mapping... so I did not try that first off...Probably should have??? If so, might have proved the maf sensor sooner?? but then got no code till the first two modules were replaced?? Your guess is as good as mine. But still got it running for less that a shop would have charged me. Around $230 in parts. And now I have the special bolts for the gm harmonic balancer. Grandma is happy again.
Use this if it helps... [u:bcb0e97671][/u:bcb0e97671]

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
