My Elantra has me perplexed. When I take off from a stop, it seems either perfect or rarely might have just the tiniest hesitation. But when the A/C is running, many times when I take off there is a miss or bogging down that seems to go away once the rpms come up. It’s an automatic. I live in an almost desert climate so I’m the summer the A/C is very important like now. I checked for codes and it shows none but I do remember that my mother told me when she was borrowing it for a time that the check engine light came on for a bit. I thought maybe tps or mass air sensor. But I could be totally wrong. Any ideas? I’m at my wits end.
