Strange RPM Drop

Have your alternator checked...sounds like it's not keeping up with the draw down on the battery.

Heya, jcb, if that was directed to me, that's currently in the works, as that was my suspicion from the moment I noticed the problem.

Did a new alternator solve it?

I agree. I charge my battery every week or 2 and it needs it. Runs nicer when charged. Full voltage feels better with a/c running. The PO's wife drove it everyday to the gym (YOGA !!!) but at my home the car stays in the garage all the time with the battery discharging.

Try this first before taking your alternator off your cars to test.

Amazon.com: Equus 3721 Battery and Charging System Monitor: Automotive

When you suspect an electrical problem, it is not easy to tell if it is the battery or the alternator. This tool can help you determine which.

I like it so much that I bought extra and give it out as gift.

If you join Amazon Prime, the 2-day shipping is free too. (There are so many "free" things AFTER you pay!!!)
