Ever since we started getting High temps here in new york (90F), I feel like my car is loosing power. Even when I keep it on P (park) car feels like its gonna shut off...Anyone has or had that problem or maybe someone knows what causes that...I change my oil regural, clean air filter, just changed spark plugs...thanks in advance

Your AC will use alot of power. If your alternator is dying, you will see results like yours. It can't keep up with the demand from your car.

Simple test: With your engine running, remove the negative cable from your battery. If the car dies, your alternator is shot. If it stays running, turn on your lights, radio and AC, let it run like that for maybe 10 mins. Again, if it dies, your alternator needs replacing.

If there is no change, take it to your dealer...

If its got the original battery its time to replace it. If not it still could be the battery or alternator?

Thats why we're all here.

When you buy a new alternator, you pay a deposit fee. When you bring in your old one, you get $ back. So its your call whether or not just to take out the old one first, and save a trip to the store.

This would be a good time to upgrade/replace your battery cables, if you haven't already.

Good luck!

When a alternator or starter is needed, it is always better to take your vehicle to a shop that rebuilds them. They bench test both before and after the rebuild. If the windings are ok, they just replace bearings, diodes, & lubricate. There is not much to them & not only is it cheaper but you have a better chance of not getting a defective one or paying the markup from a regular auto supply store.
