Hi, I know very little about cars so I am coming to this forum in the hopes that someone can provide me with some insight and direction. Over the last several weeks my car (2010 Hyundai Accent, 60k miles) started randomly stalling on me. I took it to my mechanic earlier this week and all 4 ignition coils were replaced. Yesterday I accidentally left my headlights on for about 2.5 hours and the car was completely dead. I got it jumped and drove it around for about 35 minutes. I had the battery tested at Autozone and they said it is good. Then last night it stalled in the McDonald’s line - I was able to restart it and get home but this morning it is completely dead again. Also twice yesterday after starting up the car the rpm dial wasn’t moving at all. The car was accelerating just fine but the rpm dial did not reflect this. Of the several times I drove it yesterday it only did this twice. My mechanic is closed until Tuesday. Can anyone tell me what they think is going on and what I should do? Someone told me to bring the battery to Autozone to get it fully charged, but does that explain the rpm dial not moving?
Thanks for any advice you can offer!
