Maybe you mean B0040 , because there is no B0004 ! Maybe you should think about taking your vehicle to a qualified repair shop !

I have an 88 buick LeSabre/ vin "C"/ 3.8 with a trouble code 26. It only comes on going up hill

Hi! I have enclosed 3 trouble trees for you. The code being stored is a quad driver error. Quad(which means 4)drivers control up to 4 things. They are located in the engine control module. They provide ground for the items that they control. This could mean a component that the driver controls could be bad or the computer itself. Hope this helps you!deb334a.gif911608a.gif925db0e.gif

My 2000 buick lesabre hesitates when i hit the gas

You need to get the computer scanned to see what the "trouble code" is. The light is on because the computer found an error.

1991 Buick with 3.8L Cam Sensor

The cam sensor is the "high voltage switch", more commonly refered to as the distributor.

You are probably trying to figure out why you have a cam-crankshaft correlation error code.if the distributor has been disturbed for any reason i.e. tune-up or intake gasket repair, it is not aligned exactly. Tweak it slightly and restart the engine. if the code goes history, you got it. P.S. it may even be unplugged.
