What is proper idle setting for 2000 Malibu. my Malibu wants to stall going up hills

SOURCE: Stalls out when braking quickly, worse with going down hill

Assuming that the vehicle is equipped with an automatic transmission, it looks like the torque converter lock-up system doesn't release as fast as it should, so if you brake hard, the converter is still locked up and your wheel brakes stall your engine (just like pressing ******* the brakes with the clutch pedal released on a manual transmission vehicle). Normally, when you brake hard, the lock-up should release and prevent the stall from happening. Might be a bad torque converter, or a bad lock up solenoid in the transmission... Before jumping to anything else, i'd try checking the fluid level in the transmission and an oil/filter change in the transmission. Lots of times one or the other can cure the problem.

Depending on youre mechanical ability you can spend 20 bucks for a rebuild kit on your carburator.

There tends to be many different potential issues with youre description of the problem. My best advice for you at this time, would be get the carburator re-built and check youre fuel pump/fuel filter.

But you can always go to youre local shop and get a free estimate.
