Having problems with your 1998 Buick LeSabre ?
My car a buick lesabre limited edition 1998 runs good but sometimes it dies on me all the suddent ..... any suggestions?
You got a clean air filter? If it can't breathe, it won't run well or at all. Just like you. The car run okay until it's under load (driving)? If so, the fuel filter may be clogging. This will get worse till it won't hardly run due to no fuel. Fuel pump failing? The two cars I've dealt with that had clogged filters, would run less and less well under load, acclerate slower and slower and finally just die or not start. GM car, hmmmmmm. Fuel filter may be in engine compartment. I'm not sure on placement. My Tahoe's is on a frame rail but I think you have a unibody vehicle. If that's so, probably in engine compartment or it's tucked away somewhere. It's a canister looking thing with an in and an out for fuel. That's it. Not complicated just depends on placement as to how hard it's gonna be to access it. Fuel pump is a different story. In the gas tank, tank needs to be removed and pump replaced. Hope this helps.
