if there is sparks u need to check and see it its coming from the plug wires that's about the only thing that can spark without blowing a fuse
Keep engine running idle speed
If it is a VR6 engine it might be a cracked coil pack. You can check this by spraying a mist of water over the coil pack while the engine is running. If there are cracks sparks will run on the outside of the coil pack. If you do this while it is dark the sparks are often easy to see.
If the engine is running and the alternator is good. If the engine is not running, no.
No , just when the engine is running
Get engine running. While the engine is running disconect the POSITIVE termninal from the battery. If the engine dies, the Alterntor is bad.
If the sparks are coming from the wires that fit onto the plugs change all spark plug leads. I can't understand how the engine is running at all.
The alternator - it provides a charge to the battery while the engine is running.
Is the engine running ? no
engine is running lean while eccelerating
Because it's in park.
Yes (, just be sure the engine is not running) .
