wheel bearing r&r on a windstar

99 Buick Regal 3.8L V6 (no supercharger). Often chugs on light acceleration in 2nd or 3rd gear and then shifts rather hard into overdrive. Usually only after driving for close to an hour or more and gone if left to cool off for a couple hours before being driven again. Check engine light comes on when problem exists and eventually goes off when driven without symptoms for a while. I read this in a local newspaper: "It could... be the torque converter clutch locking and un-locking for some reason. A quick test for this would be to use your left foot to depress the brake pedal about half an inch - not enough to actually engage the brakes, just enough to activate the brake switch - and hold it at that point while you gently accelerate. If the chuugle disappears during this test, the problem is with the converter clutch or its 'command' from the powertrain control module." First question would be whether the above seems reasonable. Second, of course, is if there's any kind of ball park on the cost to fix this - $200, $2000?

I put a new timing belt on a 1990 Prizm and set everything to the marks. I just want to double check timing and the manual tells you to go by sticker under hood. Well the car has been painted and the sticker is not there. Does anyone know what the timing set should be on a 1990 Geo Prizm? It is the LSI model with the 1.6 engine. Also some cars have you pull a vacum hose when you are setting timing or unplug something. Any help would be greatly appreciated.
