Sounds like a vacuum leak. Check mounting bolts on throttle body and intake manifold for tightness. Also check vacuum hoses for cracks or disconnections. Might also want to check PCV valve and air filter.
It's probably a broken engine mount. I have an 04 Alero and mine was broken. Jerking stopped when I replaced it.
is the 2000 Oldsmobile alero 2.4 l a good engine
Oldsmobile stopped making Alero in 2004 and GM stopped making Oldsmobile in 2004, so some mistake here?
If they both have a similar engine, yes
yes, a 3.4 is a 3.4, you might have to swap the fuel injection unit on top of the engine to the alero's set-up so the alero's computer will work right.
what does the engine light on the 1999 olds alero mean
By the battery.
Its on the engine near the thermostat
In a 2000 Oldsmobile Alero : Both the 2.4 litre four cylinder engine and the 3.4 litre V6 engine have a timing CHAIN
In the 2000 Alero, it is fuse 34 in the engine fuse box, which is located near the battery. You can check the same fuse for the 1999 Alero and see if that is it.
It is in the engine compartment under the hood
at the end of the top radiator hose
