After running for about 30 seconds or sitting at a light or idol an while drive the car starts sputtering. It stops for a few minutes and starts again. Any solutions

check your ECC sensor it's about 15 bucks should solve your problem it's the cheapest easiest thing to start with too narrow down the problem but I'm guessing that's what your issue is if you take it to a mechanic they're going to charge us several thousand dollars and swap out all kinds of stuff you don't need to or it could simply be your alternator is bad in your battery is draining depending on how long it's been going on
