Twice this week (once while stopped in my garage and once at a red light) the rpm's on my car started to go up and down while I was idling. They would go so low that I thought my car would stall out.
The first time was in the garage. I turned my car off and then on again and it seemed to have 'fixed' the problem. When at the red light, once I started driving again, that seemed to 'fix' the problem.
What do you think may be causing this being that it's so infrequent.
My car has 209000 miles.
My car has an automatic transmission.
– Car rev’s fluctuate when idling sometimes, happened twice in one week.
